The first rule of Sonic Pulse, I learned, is that you do not practice Sonic Pulse near the reef.

  The second rule of Sonic Pulse is that if you forget the first rule, you will know you have forgotten it because every fish within thirty meters will immediately leave, and Crabby will give you a look from under his coral overhang that communicates, without words, that he has survived eleven years in this reef through a combination of patience and low expectations, and you are currently testing the low expectations.

  “Sorry,” I said.

  “Mmm,” said Crabby.

  I took my Sonic Pulse practice to the open rubble flat two hundred meters west of the reef, which was empty, and flat, and had no coral for me to accidentally rattle loose, and most importantly had no sardines.

  Here is what I discovered about Sonic Pulse through approximately three days of increasingly controlled experimentation:

  The rebound problem was a physics problem, and physics problems respond to understanding. The pulse went outward from me in all directions the first time because I hadn’t shaped it — hadn’t thought of it as a shape at all, just a release. The second session I tried to make it directional, pointing it forward the way you’d point a flashlight, and produced something that was more a cone than a sphere. I only knocked myself sideways instead of backward. Progress.

  By the fourth session I had the geometry of it. Not a sphere. Not even a cone, exactly — more like a focused column, dense at the center, dispersing at the edges, the way the electromagnetic sense worked when I aimed it deliberately instead of sweeping. Point, focus, fire. The rebound was a fraction of what it had been. My health bar stayed stable.

  SONIC PULSE: Rank E → Rank D.

  And then I tried it on something.

  There was a clam. A specific clam that had been sitting in the sand approximately four meters from my usual hover position, registering in my electromagnetic sense as stubbornly, deeply, determinedly closed. I had tried the standard approach — settle into the sand, work at the edges — and the clam had responded by being a clam, which is to say it had done absolutely nothing while also remaining completely inaccessible.

  I focused the pulse. Narrow. Controlled. Aimed at the clam from two meters out.

  Fired.

  The clam popped open.

  I stared at it.

  I stared at it for a long time.

  Then I looked at the rubble field around me, which my heightened electromagnetic sense was telling me contained approximately — I did a rough survey — thirty-seven other closed bivalves of various species.

  SONIC PULSE: Rank D → Rank C.

  I was going to need more cave space for all the shellfish I was about to eat.

  -----

  Oscar found me on day three of what I was privately calling the Acoustic Foraging Era, when I had moved my primary hunting ground to the open sand and rubble flats west of the reef and was methodically working through a scatter of cockles with the focused efficiency of someone who has discovered a cheat code and is not ashamed about it.

  “You figured out the pulse,” he said.

  I opened my fourth cockle. Yes.

  “How far can you aim it now?”

  About six meters if I really focus. Three is more reliable.

  “And the rebound?”

  Manageable.

  Oscar did the tilt that meant he was filing information away. “The residents are going to like this,” he said. “You being out here instead of the reef edge. Less competition for the reef-side shellfish.”

  I had been starting to notice that, actually. The first week I’d been foraging the reef edge, I’d been moving through territory that a dozen other reef residents used. Nothing hostile had happened — the reef etiquette Oscar had walked me through held — but there was a particular quality to swimming through a space and feeling the electromagnetic displeasure of four different fish whose lunch you’ve just eaten.

  Out here in the open flats I had the competition of the occasional eagle ray passing through — actual eagle rays, the kind that didn’t have system interfaces or panic attacks, who looked at me with the frank uncomplicated gaze of something that had no opinions about my situation and were just trying to eat — and not much else.

  More food. Less awkwardness. Better practice range for the pulse.

  “The residents are going to like you more,” Oscar confirmed, and swam away, which I had learned was Oscar’s version of a compliment.

  -----

  I heard about the check-in two days before it happened, from Crabby, who delivered the information with the specific economy of someone who has prepared a briefing.

  “Bureau representative arrives every six weeks,” he said. “Lands on the surface above the reef. All Floor Seven cases are expected to present. Smith will conduct individual assessments and a group session. Attendance is required.”

  Required by who?

  “Smith.” A pause. “The Bureau. Arguably the existential terms of your reincarnation, depending on how you read the agreement you didn’t sign.”

  That last part was very pointed.

  “Smith is professional,” Crabby continued. “He is also a pelican, which he did not choose. He will not discuss how he became a pelican. Do not ask.”

  Noted. What does the session involve?

  “Checking in. Status updates. Smith reviews your system data — he has access, you agreed to this by accepting the system at the beginning, yes you did, it was in the initialization text, no you didn’t read it — and assesses adjustment progress.” Crabby shifted. “It is also when the Hidden Statistics Board gets updated.”

  The what?

  Crabby produced the specific energy of someone who enjoys having information. “There is a running tally among all Bureau-assigned cases in this reef of Fortune Shell finds. The reincarnate with the highest count at each check-in gets to select one stat of their choice for a temporary boost. Lasts until the next check-in.”

  I thought about my three Fortune Shells. The two successful spins. The one devastating Please Try Again.

  What’s the current count?

  “Sura has five,” Crabby said. “She has very good arms and a great deal of patience.” A pause. “You have three. Otter has two. Bruce has zero because Bruce refuses to engage with the system on philosophical grounds, which the system does not care about, which is exactly the kind of standoff Bruce enjoys.”

  So Sura wins.

  “Sura wins unless you find two more Fortune Shells in the next two days.”

  I looked at the open flats around me. My electromagnetic sense swept outward at full heightened range, covering the rubble and sand in a detailed map of buried signatures.

  Two days, I said.

  “The rubble field on the north side of the reef is largely unsurveyed,” Crabby said, very casually. “I have not been there myself, being a crab, and therefore having no information about what might be buried there.”

  I looked at him for a long moment.

  He looked back.

  “No information whatsoever,” he said.

  I went north.

  -----

  I found both shells. I’m not going to overclaim about my abilities here — the northern rubble field was genuinely rich, and the second shell I almost missed entirely because it was under a full thirty centimeters of sediment and the signal was faint at that depth. But the heightened detection had range and the new efficiency upgrades had resolution, and I pulled both shells in the two days before Smith arrived with a feeling that I was choosing to call earned confidence and other people might call obsessive foraging.

  Fortune Shell count: five. Same as Sura.

  The system noted, when I brought this up, that in the event of a tie the bonus stat selection would go to the resident with the higher Fortune Shell quality score, which was determined by the depth of burial at find-time. My second shell had been thirty centimeters deep.

  I had no idea what Sura’s deepest find was.

  The system declined to tell me on privacy grounds, which I thought was rich coming from a system that had shared my status data with a pelican.

  -----

  Smith arrived on a Wednesday.

  I knew it was a Wednesday because Otter had told me, and Otter tracked the days with the commitment of someone who had decided that if she was going to be an otter on Earth 6214 she was at minimum going to know what day it was. She had a system involving current patterns and the migratory behavior of a specific school of mackerel who apparently kept very consistent schedules.

  Smith landed on the surface above the central reef with the specific loud splash of a large waterbird making no effort whatsoever to be inconspicuous. From below I could see him in the way I saw the surface — through water-pressure and electromagnetic refraction, an impression rather than a picture — and the impression was: large. Contained. The bioelectric signature of something that had a job and was here to do it.

  He made a noise that translated, through water, as: “All cases to the surface. Now, please.”

  I surfaced.

  There were six of us. I had known the number from Sura but seeing us assembled was different from knowing it abstractly. Sura, arms folded in the way octopuses don’t literally fold their arms but absolutely can communicate with posture. Oscar, bright yellow and hovering with the surface ripple catching his color. Otter, already at the surface, treading water with the ease of someone who lived there. A fish I didn’t recognize — older, large, with the electromagnetic signature of something that had been here a long time, who Oscar murmured was Gerald the grouper, back apparently from wherever he’d been. And Bruce.

  Bruce was present in the way a thunderstorm is present. He circled at the edge of the group with his flat grievance signature running steady, fins cutting the water with the efficiency of something that didn’t have to try. He was here because he had to be here. Every movement said this.

  Smith looked us over. Up close — surface-close — he was a brown pelican with a pouch that he held slightly forward and eyes that had the quality of something that had processed a lot of paperwork and had arrived on the other side of paperwork at a state of pure calm competence.

  “Good,” Smith said. “Attendance complete. I’ll do individual assessments after the group session.” He ruffled his feathers. “General status: the reef cohort is performing within acceptable adjustment parameters. The Bureau is pleased with the Level progression of the newer arrivals—” a glance that I interpreted as directed at me, “—and notes that the integration metrics suggest higher-than-average community engagement.”

  Community engagement, I thought. I was giving Crabby rides.

  I’m getting to that.

  Bruce circled.

  “Smith,” Smith continued, “I’d like to note for the record that the Bureau has reviewed the outstanding complaint regarding magical evolution path access and has approved the non-standard Growth Track selection, which I understand has already been implemented—”

  That was fast, I said.

  “You escalated four times,” Smith said, without inflection.

  Five, I said.

  “Five times,” he corrected. “The Bureau finds persistence statistically meaningful. You may continue filing complaints if you have them. The Bureau will continue responding when they have something to respond with.” He looked down the surface. “Any group questions before—”

  Bruce lunged.

  I don’t think he planned it, exactly. Or maybe he did. The flat grievance signature spiked into something sharper for exactly half a second before his momentum was already committed — a full bull shark strike aimed directly at the pelican sitting on the surface, jaws open, the kind of strike that did not typically result in the continued existence of whatever was in front of it.

  Smith didn’t move.

  What happened instead was that Bruce hit something that was not Smith and was not water — something that closed around him with the quality of a soap bubble but the physics of something considerably more structural. A sphere of air, lifted entirely out of the surface and suspended above it, containing one very large and extremely surprised bull shark.

  Bruce floated. In the sky. In a bubble. Approximately three meters above the water.

  Everyone was quiet.

  Smith resettled his feathers. “Bruce,” he said.

  The bubble rotated slightly. Bruce’s electromagnetic signature had gone from flat grievance through spike of action to something I had never felt from him before: a rapid, shallow, entirely unfamiliar pattern that I recognized after a moment because I’d felt it from myself.

  Panic.

  “Bruce,” Smith said again, differently. “You’re okay. You’re contained. You’re not going anywhere.” A pause. “Breathe.”

  “I can’t—” Bruce’s voice came through the water-air interface strangely, carried more by the electromagnetic resonance than by actual sound. “I can’t — put me back — I need to—”

  “I’m going to put you back,” Smith said. “I’m going to put you back in thirty seconds. I need you to hear me first.”

  The bubble rotated. Bruce’s fins moved against the air the way they moved against water — reflex, muscle memory, finding no purchase.

  “You are okay,” Smith said. “You are currently safe. The threat you responded to was not real — I cannot be eaten, I have Bureau protections that have been in place since the incident in the North Pacific which we don’t discuss — and you are going to be back in the water in twenty seconds and everything is going to be exactly as it was.”

  The panic signature slowly, incrementally, stepped down.

  “There you go,” Smith said. “There.”

  He lowered the bubble to the surface. Dissolved it. Bruce hit the water and dove immediately, going deep, and for a moment all any of us could feel of him was his signal dropping toward the seafloor and then holding there, still.

  None of us said anything.

  Smith looked at the water where Bruce had been. Something in his posture, just briefly, was not the posture of a Bureau representative doing his job. Then it was again.

  “Individual assessments,” he said. “Otter, you’re first.”

  The story has been illicitly taken; should you find it on Amazon, report the infringement.

  -----

  My individual assessment was short. Smith reviewed my level progression — eight, by the time of the check-in, I’ll get to how — my skill acquisitions, my combat record (one defensive stab of a lobster who had been about to pinch me, one sonic blast of a shark, a number of shellfish whose moral status the Bureau apparently did not factor into combat metrics), and my community integration score, which the Bureau measured in ways I didn’t fully understand but which Smith described as “notably high for the timeline.”

  I helped Crabby get to places he couldn’t walk to. This had started as a favor.

  Here is how it became a thing:

  Crabby had mentioned, about a week into my reef life, that there was a shellfish scatter in the eastern rubble field he hadn’t been able to survey in three years because the route there required crossing an exposed sand flat that his crab legs couldn’t navigate without unacceptable predator exposure. I had offered, mostly out of the specific generosity that comes from owing someone information favors, to bring him along.

  He had climbed onto me.

  This was strange. Briefly. And then it was not strange in the way that things stop being strange when they become normal, which in my life was now happening on an accelerated timeline. A small ancient crab riding on a flat ray, moving through the reef at a pace set by the ray and navigated by the crab, who had eleven years of reef knowledge and a detailed mental map of every shellfish colony on the south-facing slope.

  The survey had been productive for both of us.

  EXP: +12, the system noted. For reef service.

  The next day Mr. Parrotfish — and he did introduce himself as Mr. Parrotfish, with the tone of something that had decided on a title and was not negotiating — asked if I could take him to the cleaning station on the eastern side, which was his preferred station but was inconveniently located relative to his current territory after a boundary dispute I was not going to ask about.

  I had taken him to the cleaning station.

  EXP: +8.

  SKILL ACQUIRED:

  ? REEF HELPER [PASSIVE] — Rank F

  Assists reef community members in navigation and resource access.

  Increases EXP from community service actions.

  Passive effect: Slowly improves local reputation. Decreases ambient wariness from reef residents.

  I read that last line twice. Decreases ambient wariness.

  I thought about the sardines.

  I thought about them very specifically.

  Then I thought: not yet. Let it build naturally. The skill says slowly. I will be patient.

  I was not patient. But the skill worked anyway, in the background, and by the time Smith arrived for the check-in I had a semi-regular roster of reef residents who had discovered that the new ray could be asked to go places. Crabby, who used me as a survey vehicle. Mr. Parrotfish, who was extremely particular about his cleaning station and would not discuss why. A school of juvenile damselfish who wanted to travel to the far side of the reef and back as a group trip for reasons I suspected were social rather than practical but did not interrogate. An elderly sea turtle named Margaret who appeared once, accepted a lift across the reef as though she had expected it, thanked me with the dignity of a retired headmistress, and disappeared.

  I had not seen Margaret since. Crabby said this was normal. Margaret moved in long arcs.

  The EXP was consistent. The reputation metric climbed in ways I couldn’t directly measure but could feel in the way the reef felt — less wariness in the electromagnetic signatures when I entered a new section, less reflexive flinching from small fish at my approach. Even Mr. Parrotfish, who had initially made eye contact with the energy of someone reluctantly using a bus service, had started to acknowledge me with what I was interpreting as a nod.

  “Your community metric is the highest we’ve recorded for a reef case at this progression stage,” Smith told me.

  I help people move around, I said.

  “Yes,” Smith said. “That’s what the metric measures.” A pause. “It also measures the Sonic Pulse incident with the sardines, which is flagged in your record as a — quote — ‘disproportionate response to a low-level nuisance behavior’ with a note that the outcome was considered acceptable given the resolution.”

  The sardines had, after the incident, added me to a category of threats they apparently treated as *absolutely do not approach*, which meant they no longer followed me anywhere. The transition from thirty sardines narrating my location every single morning to complete sardine silence had been one of the more dramatic quality-of-life improvements of my reef tenure.

  I didn’t regret it.

  “The Bureau does not officially endorse sonic pulse deployment against schooling fish,” Smith said, in the tone of someone reading from a document, “but notes that the behavior has not recurred and that the subject demonstrated adequate control of the ability in a precision application scenario.”

  I will take that, I said.

  “Fortune Shell count: five.” Smith looked at me. “Tied with Sura.”

  I know.

  “Sura’s deepest find was twenty-two centimeters.”

  Mine was thirty.

  Smith made a notation with a bill that somehow conveyed the impression of a pen. “Congratulations. You have this cycle’s Hidden Stat bonus. Which stat would you like?”

  I thought about it seriously for approximately four seconds.

  Intelligence, I said.

  Smith noted this. “Done. That will apply until the next check-in.” He looked at me for a moment. “Also — Bruce.”

  I looked at the reef. Bruce’s signal was still deep, still slow, still there.

  I know, I said.

  “He’s not—” Smith paused, and again there was that brief non-Bureau-representative quality in his posture. “He made his choices. He believes in them. But he’s not as resolved about them as he presents.” He picked up a fish from somewhere in his pouch area, ate it with the businesslike efficiency of something that had maintained its own biology through all of this, and resettled. “Just something to know.”

  I already knew it, I thought. But I filed it somewhere important anyway.

  -----

  The current system had been there the whole time. I just hadn’t known to look for it.

  Otter mentioned it, actually, by accident, while she was telling me about a foraging trip she’d taken three weeks prior. She described a route that should have taken her an hour taking twenty minutes because she’d caught a current on the outside edge of the reef that runs — she’d gestured vaguely west with a paw — *that way*, fast, and then curves north.

  I had gone to find it the next day.

  It was there. A column of moving water running along the outer reef edge, not visible, not anything I could have navigated by sight, but absolutely legible in the electromagnetic-pressure sense — a different temperature, a different density, moving at a pace that was genuinely fast compared to the ambient reef water. And it wasn’t alone. Following it north I found it connecting to a second current, and that one to a third, and what resolved in my sense was less a single highway and more a network — slower lanes and fast lanes and cross-currents that connected distant points of the reef the way shortcuts cut through neighborhoods.

  SKILL ACQUIRED:

  ? CURRENT READING [PASSIVE] — Rank F

  Identifies and navigates marine current systems.

  Reduces active swimming energy cost in favorable currents by 30%.

  I went home and told Oscar.

  Oscar was quiet for a long time.

  “You can feel the currents,” he said.

  I mapped three of them this afternoon.

  He was quiet again. Then: “I’ve been navigating by landmark for eight months.”

  You didn’t feel them?

  “I’m a fish,” Oscar said. “A normal fish. I don’t have—” he gestured vaguely at the entirety of my sensory apparatus. “I know they’re there. I find them by swimming into them.”

  I thought about this. I could show you where they are. You could learn the entry points.

  Oscar tilted. For a long time. “Yes,” he said finally, with the specific dignity of someone accepting help while maintaining their composure. “That would be useful.”

  We spent an afternoon mapping the current network together, me following the signals and Oscar learning the visual and physical landmarks that corresponded to each entry point. It was — actually a good afternoon. The best kind of work, where the product is something that exists now that didn’t exist before and is useful to someone other than yourself.

  EXP: +15. The Reef Helper skill had opinions about what counted as community service.

  The current discovery changed my foraging range significantly. I could reach the far rubble flats in a third of the time. The deep sand channels north of the reef, which had been a day trip before, became a casual morning run. The Fortune Shell finds accelerated — my range was wider, my detection was sweeping new territory, and I found two more shells in the week after the current discovery that I was saving against the next check-in like a strategic reserve.

  The reef residents noticed I was bringing in food from further out. This seemed to fall under the general category of things they found acceptable. Mr. Parrotfish made something that might have been an approving noise.

  -----

  The Bruce situation resolved itself in a way I had not predicted, which was by Bruce attempting to eat me and me hitting him with a Sonic Pulse at close range, and then both of us having a conversation in the approximately thirty seconds it took him to stop being stunned.

  He had come in from behind again. I was in the open water west of the reef, running the current highway north, and I felt him — that dense muscle signature, that flat grievance — about two seconds before his trajectory made his intention obvious. I had thirty meters on him and a current to ride.

  I didn’t run.

  I don’t know why I didn’t run. Maybe it was what Smith had said. Maybe it was eleven days of knowing Bruce was out there and thinking about Crabby saying *he’s not as resolved as he presents*. Maybe it was the specific and irrational impulse of someone who had grown up reading books about complex antagonists and had developed an instinct for the moment when running stops being the answer.

  I turned around.

  Bruce pulled up short. Not because he was startled — I don’t think much startled Bruce. But because I had turned to face him and that was apparently not in his behavioral database for prey.

  We looked at each other.

  Then I fired the pulse.

  Close range. Controlled. The Rank C version, precise enough to be directional. It hit him in the snout — which is, for a shark, where the most sensitive electroreceptors are — and Bruce went sideways and briefly still with the specific quality of something whose sensory systems had just been comprehensively overloaded.

  Four seconds. The same four seconds I’d spent in the sand the first time I’d used it.

  When he came back online I said: I’m not going to keep running from you.

  Bruce looked at me. His electromagnetic signature was doing something I hadn’t catalogued before — not the flat grievance, not the hunting focus, not the panic from Smith’s bubble. Something that was several things at once, layered in a way that felt complicated.

  “You should,” he said.

  I’m a Floor Seven case. You know that.

  “I know.” His fins moved, a minimal adjustment, holding position. “Doesn’t mean I won’t eat you.”

  You just tried, I pointed out. How did that work out.

  A long pause.

  “My snout hurts.”

  I know. I’m sorry about that.

  Another pause, longer. “Why are you sorry.”

  Because I didn’t want to hurt you. I just needed you to stop.

  The layered signal did something — shifted in a direction I was learning to read as *not what I expected*. “You didn’t want to hurt me,” Bruce said. Not a question. More like he was testing the sentence to see if it was real.

  No.

  “Most things I’ve tried to eat would not have said that.”

  I’m not most things.

  We stayed in that patch of open water for a while. Bruce’s signal gradually settled back toward the flat grievance, but there was something different underneath it now — a quality I couldn’t name except to say it felt less sealed.

  “The Smith thing,” he said eventually.

  You don’t have to talk about it.

  “I know I don’t.” His fin moved. “I don’t like heights.” A pause. “I didn’t think that was going to be a problem when I chose this.”

  A shark with a fear of heights. There was something so specifically, painfully human about it that I didn’t know what to do with it for a moment.

  Heights are hard, I said.

  “Everything is hard,” Bruce said, with the absolute conviction of someone who has believed this for a very long time. “But heights are worse.” A pause. “Your pulse — is that the thing that makes the noise.”

  Yes.

  “It’s annoying.”

  I know. I’ve knocked myself out with it.

  Something changed in the signal again. Not quite amusement. But adjacent. “Did you.”

  First time. Sent myself three meters into the sand.

  The pause was longer this time. “That’s—” and then nothing, and the signal held something that I would have called *almost* on any emotion he wasn’t used to feeling.

  I waited.

  “You should come eat clams near the reef sometimes,” Bruce said. “Where I can see you.”

  You want to see me?

  “I want to know where things are,” he said. “That’s different.”

  I thought about it for exactly as long as it deserved. Okay, I said. I can do that.

  “Don’t make a thing of it.”

  I won’t.

  “And if I try to eat you—”

  Hit you with the pulse, I know.

  “Good.” A pause. “That’s acceptable.”

  He turned and went back toward the open water.

  I stayed in the current for a moment, feeling the shape of the conversation settle.

  Then Crabby, who had been getting a lift to the eastern survey site and had been present for the entire exchange, said from his position on my back: “Hm.”

  Don’t, I told him.

  “I wasn’t going to say anything,” Crabby said.

  “Hm,” he said again, quietly, to himself.

  -----

  The grouper arrived on a Friday.

  I was in my cave, reading Chapter 44 — Lord Valdris had just engineered the peaceful overthrow of two provincial governors simultaneously using nothing but a forged letter and the power of debt, and I was genuinely taking notes in the mental library the system had set up for me — when the electromagnetic sense resolved a new signature at the cave entrance.

  Large. Slow. Old. The signal of something that had been somewhere long enough to believe it had property rights.

  I looked up from Chapter 44.

  The grouper was large the way old reef fish get large — not dangerous-large, but *settled*-large, the kind of size that comes from decades of being good at staying alive. It had the electromagnetic signature of something that had opinions and the mass to back them up.

  “Out,” it said.

  I blinked. Gerald?

  “This is my cave. You are in my cave.” Gerald looked at the cave. At the kelp art Otter had started attaching to the walls about two weeks in, which now covered most of the back chamber in a way that was honestly quite decorative. “What is that.”

  Art, I said.

  “Get out of my cave.”

  I looked at Gerald for a moment. Then I looked at my cave. I had been in this cave for — I counted — thirty-one days. I had carried eleven reef residents across various distances in the service of community building. I had mapped three current systems. I had knocked out both a shark and a sardine with my face and earned one of them as something that was potentially close to a friend. I had survived two weeks of sardine surveillance, three panic attacks, one Level 5 evolution debate, and a pelican with Bureau clearance.

  I pulled up my status.

  I looked at my stats for a long moment.

  Level 8. Mana, unlocked and growing. Two new skills. Thirty-one days of building something in this reef and in this cave and in this version of my life.

  I looked at Gerald.

  This is my cave now, I said.

  Gerald stared at me with the complete incomprehension of something that had not encountered resistance in a very long time. “You are a ray,” he said.

  I am an Owl Ray, I said. There’s a distinction.

  “This cave—”

  Has Otter’s art in it, I agreed. And my Home Base designation. And thirty-one days of occupation, which in reef terms I am going to argue constitutes adverse possession.

  Gerald’s electromagnetic signal did something complicated. “Adverse possession.”

  I’ve been here. I’ve been useful. I’ve been here continuously and in good faith and with no knowledge that the prior occupant was returning.

  I had not thought before this moment that fourteen years of reading books that included the occasional chapter of fantasy politics and inheritance law would be relevant to my new life. I was reassessing that.

  “The grouper can sleep in the secondary cave two structures east,” said Crabby, from somewhere nearby. I hadn’t realized he was in listening range. “I believe it’s available.”

  Gerald looked at Crabby. At me. At Otter’s kelp art.

  “That art is strange,” he said.

  It grows on you, I said.

  Gerald made a sound that I was choosing to interpret as ‘I am conceding this point while maintaining my general dignity’ and left.

  I went back to Chapter 44.

  -----

  The anemone garden was an accident.

  In my defense, the current that runs east-northeast along the outer reef edge is fast and efficient, and I had been riding it for approximately forty-five minutes at a pace significantly improved by the Efficient Swimmer skill, and the timing felt right, and I had been enjoying the speed, and I had *not* been reading The Vampire Murderer this time — I want that on record — I had just been going slightly faster than was perhaps ideal for a reef section I had not fully surveyed.

  The current turned.

  I did not turn with it in time.

  I came out of the fast water into — a garden. There was no other word for it. A dense, carefully arranged colony of anemones, their tentacles moving in the current in a way that was either very beautiful or deeply threatening depending on your perspective, with small bright fish moving between them in patterns that had the specific quality of not being random.

  I had stopped in the middle of it.

  The electromagnetic sense mapped the garden immediately: multiple clownfish, distributed throughout the colony, their neural signatures running hot with the specific pattern of something that has noticed an intrusion and is processing options.

  And then the largest one — settled near the center of the colony, signal dense with the quality of something that had been here long enough to have a whole philosophy about it — turned to face me.

  “Do not move,” she said.

  I did not move.

  “You are in the garden,” she said, in the tone of a person telling you a fact they feel should not need to be stated.

  I know, I said. I’m sorry. I came off a current and I missed the turn.

  “You missed the turn.” She looked at me with an assessment I had started to recognize across species — the specific evaluation of something that was deciding in real time what category you belonged in. “You’re the Owl Ray.”

  News travels.

  “Oscar told me. Oscar tells everyone things.” A pause. “I’m Coral. I run this garden.” She said it the way charge nurses say *I run this ward* — not as a boast, as a fact, delivered with the expectation that you will integrate it immediately and adjust your behavior accordingly. “You’ve heard the rule about the garden?”

  Oscar told me. No hunting, no aggression, non-aggression guaranteed in return.

  “No *unannounced entry*,” Coral said. “Also no hunting. Also no aggression.” She looked at the garden around me — the careful arrangement, the anemones, the fish moving in their patterns. “This is a managed ecosystem. We have seventeen resident species, four visiting species on rotating schedules, and two fish who are here for medical reasons. Every new presence is a variable.”

  I understand, I said. I’m genuinely sorry.

  Coral looked at me for a long moment. Then: “The current that runs east-northeast curves at the fifty-meter marker. There’s a feather star colony at the curve. Learn it.”

  I will.

  “You can’t leave tonight,” she said. “The current system’s shifted — the storm three days ago moved the east channel. You came in on it, you can’t go back out until it resets. Overnight.” She said this without apparent frustration, in the way of someone who has incorporated many logistical variables into a working system and has capacity for one more. “You can stay if you’re useful.”

  Useful how?

  “We run a predator watch at night. The outer edge of the garden needs monitoring — something large comes through on irregular cycles and disturbs the eastern anemone beds. Your electromagnetic range would cover the perimeter.”

  I looked at the garden. At Coral. At the anemones moving in the current.

  I can do that, I said.

  “Good.” Coral turned back to whatever she had been doing. “Dinner is at the second current shift. Don’t eat anything you haven’t been told you can eat. Don’t touch the anemones. If anyone asks, you’re here as garden security.” She paused. “And don’t bother Jack.”

  Who’s Jack?

  Coral nodded — or the clownfish equivalent, a movement of her whole body — toward the far edge of the garden, where a narrow crack in the limestone disappeared into shadow. The electromagnetic sense resolved a signal in there: sinuous, long, dense with the particular neural signature of something intelligent in a way that ran along different channels than the fish I’d been meeting.

  An eel.

  A large one. The signal was old — not old like Crabby, but *experienced*-old, the kind that means something has been through enough to have a whole interior landscape built up from it.

  “Jack came to the garden two months ago,” Coral said. “He has not told me where from. He is quiet, he is respectful, and he is extremely unhelpful about his background.” She looked at the crack in the limestone. “He watches the west edge at night. You have the east.”

  I looked at the west edge. The signal in the crack was still, and very aware.

  I’m Mika, I said, in the direction of the crack. In case you wanted to know.

  There was a pause. Long enough that I thought there wasn’t going to be an answer.

  Then: “I know,” said the eel. A voice like water moving through very old stone. “I’ve been watching you figure out this reef.”

  For how long?

  Another pause. “Since the shark,” Jack said. “The first one.”

  I thought about that. He had been here the whole time. Watching. Not introducing himself, not joining the check-ins or the foraging or the current-mapping afternoons. Just — watching.

  Why now? I asked.

  The signal in the crack moved slightly. Just a shift. Like something deciding something.

  “I haven’t decided yet,” Jack said. “Ask me in the morning.”

  I turned to face the east edge of the garden. The night current moved through the anemones. Somewhere out in the open water, Bruce was swimming his circuits, unhappy and consistent.

  The garden was quiet.

  I started my watch.
