The forest edge in winter looked like a different place than the forest edge in autumn.

  Theron had been noting things like this without quite meaning to — the way a location changed with the season, the quality of light, what grew where and when and why. He'd been a city person most of his life, formed by indoor spaces and climate-controlled corridors, and the amount of detailed environmental attention this world required of him still occasionally surprised him. He knew the forest edge now the way he'd once known the layout of his operating room. Which was a comparison that wouldn't mean anything to anyone here, but which was true.

  Sora moved through the low winter scrub with the ease of someone born to it, which she had been. She was faster than him in these conditions and she knew it, and she'd learned to not make it obvious in a way that suggested someone had told her at some point that making things obvious wasn't kind.

  "Here," she said, stopping at a stand of feverbark he hadn't noticed, three feet off the path under a bare-branched elder.

  He looked. Good bark — the right color, the right texture, the dry-winter smell that meant it was concentrated rather than diluted. He crouched beside it and started to work, and after a moment Sora crouched on the other side and did the same, both of them working inward from opposite ends of the stand in the efficient silence they'd developed for tasks like this.

  She was taking the younger branches, he noticed. Bark from younger branches worked faster — she'd told him that last week, the thing she'd learned from Mora. She was applying it automatically, without thinking about it, which meant it had moved from knowledge to habit, which was the whole point.

  He didn't say anything. Saying it would make it smaller somehow.

  They worked until the pouch was full, which took about twenty minutes, and then started back toward camp in the low grey morning light.

  The trader was already there when they returned.

  Not a Broken Spear raider — the distinction was immediately clear. He was older, for one, maybe fifty, with the weathered patience of a man who had spent a great deal of his life moving between places and had made his peace with what that required of a person. He carried a frame pack of the kind Theron had learned to identify as trade goods — organized, balanced, the contents wrapped individually against weather. He was sitting by the main fire with a cup of something hot, talking to two of the tribe's women with the easy fluency of someone who'd done this before and knew which conversations mattered.

  Dorn was lurking nearby with the particular quality of excitement he was bad at concealing.

  "Theron," he said, when he saw them coming. He waved with too much enthusiasm for the temperature. "Come. Come now."

  Sora looked at Theron. He shrugged. They came.

  The trader's name was something with too many consonants for Theron to catch cleanly — he'd learn it eventually, or he wouldn't. The man looked at Theron with the professional curiosity of someone who spent a living reading new places and people quickly, and made a small nod that wasn't quite a bow and wasn't quite casual, a middle thing that Theron returned with what he hoped was appropriate weight.

  Then the trader said something to Dorn.

  Dorn's face did the thing it did when something delighted him — not loud delight, which he was also capable of, but the quieter kind that meant it was genuinely good rather than just surprising. He turned to Theron with the expression of a man delivering news he'd already decided was excellent.

  "Broken Spear," he said. "They tell people. About you."

  "What do they say?"

  "They call you—" Dorn stopped. Looked back at the trader, said something, got a confirmation. Turned back. "Ghost Healer."

  Theron waited.

  "Because," Dorn continued, working it out, "you come from—" the gesture he used when he meant nowhere specific, the void before arrival, "—and you touch dying people. Without fear." He made a ghost-adjacent motion with his hand, which mostly looked like he was waving something away. "Ghost."

  Theron looked at the trader. The trader was watching him with the mild professional interest of a man who'd delivered many pieces of news in his life and had learned that people's reactions were usually more interesting than the news itself.

  "Ghost," Theron said.

  "Ghost Healer," Dorn said, correcting the pronunciation slightly.

  Theron turned this over. The ghost part he understood — he'd appeared from nowhere, he treated people without hesitation, he didn't behave the way a man from any known tribe should. From the outside, that added up to something between spirit and stranger, and the word they'd landed on was probably the most honest shorthand available.

  "I don't love ghost," he said.

  "Ghost is good!" Dorn was genuinely baffled by this reaction. "Ghost means—" he made a significant gesture, "—not ordinary. Powerful. From other place."

  "I know what it means. I'm just—" he paused. "Not a ghost."

  "No," Dorn agreed, the way someone agreed with a thing that was technically true but missed the point. "But Ghost Healer is good name. Better than—" he made a gesture that communicated vague outsider with no particular qualities.

  That was fair, actually.

  "Ghost Healer," Theron said again, testing the shape of it.

  The trader said something, and Dorn translated: "He says it has gone past Broken Spear now. River people know it. Some camps east, past the stone ridge. Ghost Healer who lives with Ash Tooth."

  Theron looked at the main camp — the healing spot under its overhang, the flat boulder with the organized supplies, Sora already back there and unpacking the morning's feverbark. The tribe going about its morning in the winter quiet. The fire at the center, the shelters around it, the carved marks on the rock face nearby that he still couldn't read.

  "Ghost Healer who lives with Ash Tooth," he repeated.

  "Yes." Dorn seemed pleased with this. "You are known now."

  The trader had brought gifts from the Broken Spear — salt, wrapped carefully in treated hide, and two obsidian blades that caught the winter light with the particular sharpness of very good stone. Theron touched one of the blades and thought, medical-grade obsidian scalpels, which was a thought that would have meant something to about fourteen people on the planet he came from, and which he filed away for later consideration.

  This story has been taken without authorization. Report any sightings.

  He thanked the trader with what he hoped were the right words, and went back to the healing spot, and thought about the name for the rest of the morning.

  The boy arrived just before midday.

  Theron noticed him first at the edge of the healing spot's shadow — standing in that particular way, the half-committed stance of someone who had come with a purpose and was now reconsidering whether the purpose was worth it. He was maybe thirteen, with a hunter's build already forming on a boy's frame, and the expression of someone who had decided to keep his face neutral as a strategy.

  He had his right wrist held at a careful angle.

  Theron glanced at Sora, who was already glancing at the boy with the quick assessment she'd developed. Her eyes went to the wrist immediately — she'd learned to read bodies the way Theron did, the held-careful angles that meant pain.

  "Sprain," she said quietly.

  "Probably," Theron agreed. "Go ahead."

  She looked at him. He made a small gesture — yours — and picked up his notebook as if he had something to do in it, which he did, but not urgently.

  Sora straightened, turned to the boy, and said: "Come."

  The boy looked at her. Something moved in his expression — she was his age, which he clearly hadn't expected. He glanced at Theron, then back at her.

  "The healer—" he started.

  "Is busy," Sora said, which was a reasonable description of a man writing in a notebook. "Come."

  The boy came, in the manner of someone making a tactical decision to cooperate for now. He sat on the stone that patients sat on. He held out his wrist with the careful dignity of a person trying very hard not to show how much something hurt.

  Sora crouched in front of it. Her hands moved the way Theron had taught her — careful, systematic, no wasted movement. She turned the wrist slowly, palpated along the tendons, pressed at the specific points that would tell her what was strained and what wasn't. The boy kept his face neutral, which cost him something at one particular point that he managed to cover with a brief look at the sky.

  "Not broken," she said. "Sprain. Here—" she pointed at the specific point, "—and here."

  The boy looked at the points. "How do you know?"

  "Broken bone moves wrong. This one moves right but hurts." She was already reaching for the cooling compress — wet hide, kept in the shade. "Hold. Keeps the swelling down."

  He held it. He looked at the compress, then at her, then at Theron — who was giving his notebook the attention of a man who was definitely not listening to any of this.

  "You're young," the boy said, in the tone of someone making an observation he expected to be challenged.

  "Yes," Sora said, unbothered. She was already preparing the binding strip. "You're also young. You still sprained it."

  A short silence. Then: "I'm Kael."

  "I know." She did know — she knew everyone in the camp, the way people who paid attention knew everyone. "Theron taught me. I'll bind it. Firm but not tight. Three days, don't hunt." She looked at him. "Yes?"

  Kael looked at the wrist. Looked at her. The neutrality had developed a slightly different quality — the kind that meant something had registered and was being processed. "My father won't be happy."

  "Your wrist will be less happy if you hunt on it." She started the binding. "Tell your father the healer's apprentice bound it. He can be unhappy with me."

  Theron kept his eyes on his notebook. He was writing nothing in particular and doing it very carefully.

  The binding took four minutes. Sora worked through it cleanly — the tension right, the coverage right, the tuck at the end that kept it from unraveling placed exactly where he'd shown her. When she finished she said: "Can you move your fingers?" He moved them. "Good. Pain?"

  "Less."

  "Good." She stood, dusted her hands off, went back to the feverbark she'd been sorting. Done. Next.

  Kael sat on the patient stone for a moment longer than necessary, holding his bound wrist, looking at the healing spot with an expression Theron couldn't fully read from his peripheral vision.

  Then he stood and left.

  Three days later, he came back.

  Theron was there. So was Sora, because Sora was always there. Kael walked to the edge of the healing spot and stopped, and looked at his wrist, which was clearly better — the swelling down, the movement easier — and then looked at Sora.

  "It's better," he said.

  Sora looked up from her work. "Yes."

  "You said three days."

  "I said three days."

  A pause. He wasn't holding it out for inspection, wasn't presenting an injury. He was just... standing there. Looking at the herbs on the flat stone. Looking at Theron's notebook. Looking at the organized layout with the particular attention of someone who had come back to look at a thing they'd been thinking about.

  Sora watched him with the specific expression of someone who had clocked something and wasn't sure what to do with the information.

  "Anything else?" she said. Not unkindly. Just: state your purpose.

  Kael appeared to weigh his options. Then he said: "How do you know which herb is which?"

  Sora looked at the herbs. Looked at him. Her expression moved through several stages before settling somewhere between patient and skeptical.

  "You learn them," she said.

  "How?"

  "Someone shows you. Then you remember."

  Kael looked at the herbs again. His jaw had the set of someone who had asked the question they actually came to ask and was now seeing what the ground looked like after.

  Theron, who had been watching this from a studiedly neutral position, said nothing. Sora glanced at him. He gave her the smallest possible shrug, which she read correctly as your call.

  She turned back to Kael. Looked at him for a long moment with the assessment she'd developed from watching Theron assess patients — not the injury, the person.

  "Can you come back tomorrow?" she said finally.

  Kael blinked. "Tomorrow."

  "Morning. When the light is good." She paused. "Don't tell your friends."

  He seemed briefly startled by this. "Why?"

  "Because if they come to watch you learn herb names you won't learn anything." She went back to the feverbark. "Tomorrow. Morning."

  Kael stood there for another moment. Then he left — in the manner, Theron thought, of someone who had gotten something they'd wanted without quite admitting they wanted it.

  He waited until the sound of footsteps was gone.

  "Three days," he said. "You knew he'd come back."

  Sora didn't look up. "His father's a good hunter. He's going to be a good hunter. Good hunters pay attention to things that work."

  "And?"

  She sorted two feverbark bundles into their correct positions. "And he watched the whole thing when I was binding his wrist. Not his wrist. The way I was working. He was watching the way someone watches when they're trying to understand it." She paused. "I know what that looks like."

  Theron looked at her. She was thirteen and she had just correctly identified a future student by reading his attention patterns while simultaneously treating his injury and he was, he realized, going to have to adjust some of his assumptions about what she was and wasn't ready for.

  "You learned that from me," he said.

  "I learned a lot of things from you." She finally looked up. "That's the point, isn't it?"

  He didn't have an answer for that. She didn't seem to need one.

  That evening Dorn came by with fish and the comfortable settling energy of a man who had decided the day had gone well enough to enjoy the end of it. He dropped down at the edge of the healing spot and started unwrapping the fish with the expertise of long practice.

  "Trader gone," he said. "Left at midday. Heading south." He poked at the fish. "He say he'll tell people. About Ghost Healer."

  "More people knowing," Theron said. "Good or bad?"

  Dorn considered this with genuine seriousness, which was something Theron had learned to recognize — the difference between the Dorn who was thinking and the Dorn who was performing thinking, and they were not the same. "Both, maybe," he said finally. "More people come here. More work for you. Also—" he made a gesture that encompassed the camp, the allied territory, the general outward direction of the world, "—more people leave Ash Tooth alone. Because Ghost Healer is here. Because you touch their hurt people."

  Theron looked at the fire.

  "Ghost Healer," he said, not quite to anyone.

  Sora, sitting nearby with her notes, said without looking up: "I call you Theron."

  He turned to look at her.

  She met his eyes briefly. Not the statement of a child insisting on something smaller — just information, delivered plainly. Out there you are a name that travels. Here you are a person I know. Those are different things and the second one is what matters.

  "That's better," he said.

  She nodded and went back to her notes.

  Dorn looked between them. Then he looked at the fish, which needed attention, and gave it some.

  The fire built up as the winter evening settled in, the cold finding the edges of everything and the warmth finding the center, and Ghost Healer sat between the two of them and thought that being known by a useful name where it traveled and by your actual name where it mattered was probably the best arrangement a person could have.
