By the third day after the fever broke, River was at the front of the column.
Not because the arm was healed. Because the alternative was staying in the middle and knowing that the decisions were being made forty feet ahead of her, in terrain she couldn't see, by people she trusted but who weren't her. The arm throbbed when she held it wrong. She held it right.
Cal said nothing when she moved to the front. He adjusted his positionâleft flank instead of leadâand let her take the trail. He'd known she was coming. She'd known he'd known. Three days of the fever and the aftermath had made them fluent in each other's patterns in a way that happened when you spent enough time in genuine emergency together.
The supplies were a problem.
She'd known it abstractly for daysâthe packs getting lighter, the rationing protocol Sable had implemented on the third day of the march. But walking at the front of the column on the sixth day, she felt it in what she was hearing: children who'd stopped complaining because complaining required energy. Adults who'd gotten quieter. The particular flat tone of people who were running down.
She asked Sable for the numbers at the midday stop.
Sable gave them to her in the direct agricultural chief's wayânot dramatized, not softened, just stated. Two days of food at current rationing. Three if they cut again. The water situation was fineâmountain terrain had streams. The food was a cliff.
"The structure," River said.
"If it has food storage, yes. If it doesn'tâ" Sable looked at the trail north. "We'll need to make decisions about foraging. This terrain has game. Not enough for this group, but some. Cal's been looking. He thinks he can get two, maybe three animals a day if we give him scouts."
"Take two scouts from Dara's rotation," River said. "Have Cal start now."
She moved on.

Vance was walking today. She'd been walking in the rearguard position, which was unusualâshe spent most marches near the front where she could monitor River and the wounded and the cold cabinet. Today she was at the rear and she looked like she was thinking instead of walking, which for Vance was the normal state.
River dropped back to walk with her.
"The structure Cal saw," River said. "You have thoughts."
Vance glanced at her. "What makes you think I have thoughts."
"You've been at the rear for three hours. You're not watching anything back there. You're working through something."
Vance was quiet for a moment. Then: "What do you know about Cascade Station?"
River didn't know what Cascade Station was. She said so.
"Pre-Collapse research installation," Vance said. "Pacific Northwest corridor. Government-contracted, CDC-adjacent work. Weâ" The "we" that was her distancing mechanism. "There were multiple sites established in the northwest. Cascade Station was the northernmost. Remote. High elevation. Built to continue research if the southern facilities were compromised."
River looked at her. "You think that's what Cal's structure is."
"I think the description matches. Large, intact, high windowsâthose are laboratory specifications. Large windows for natural light in spaces where artificial power was supplementary." Vance's voice was careful. Clinical but carrying something underneath it. "If Cascade Station is intactâif the people who built it maintained itâit would have food storage. Cold storage. Medical equipment." A pause. "It would have records."
"What kind of records."
Vance looked at the trail ahead. "The kind that tell you why your blood is the way it is," she said. "Among other things."
River walked for a while. The column moved around herâpeople picking their way over the terrain, the particular shuffle of a long march in its second week.
"You were there," River said. Not a question.
"I worked there briefly. Before the Collapse. Beforeâ" She stopped. "It's a long explanation and I told you I would give it when we had more information. I'm still committed to that."
"Is the Sanctuary at Cascade Station?"
Vance looked at her sharply. "What makes you ask that."
"Because you're telling me about a government installation in the Pacific Northwest with food and medical equipment and records about my blood. And you've been going to the same destination I've been going to for the same reasons." River stopped walking. Let the column flow past her. "Are we talking about the same place?"
Vance stopped too.
The column moved around them. Children, adults, the elderly cluster with Mira's shepherding. Tak and his bolt wound. Adela doing Adela things. All of them moving north toward something.
"I don't know," Vance said. "The Sanctuaryâas a concept, as what you've been told to reachâI don't know what it is exactly. I know what Cascade Station is. If they're the same place, I'll recognize it when I see it." She held River's gaze. "But Riverâif it is Cascade Stationâwhat you find there is going to be complicated. What's there is notâit's not simple hope. It's answers. And some of the answers are going to be difficult."
"I know answers are complicated," River said. "I've been collecting them for a year."
"Not like these." Vance's voice was as flat as it ever went. "Like these, you haven't."
River looked at her. At the clinical mask that wasn't quite full right now, the edges showing the person underneath.
"I'll handle them," River said.
Vance nodded. Turned. Resumed walking.
River walked beside her.
"One thing," River said. "Now. Tell me one thing."
Vance thought about it for three steps.
"Your parents didn't die randomly," she said. "The why and howâthat's for Cascade Station. But I want you to know that what happened to them mattered. They mattered. And what they didâwhat they builtâis why the Sanctuary exists if it exists." She paused. "That's all I can give you now."
River's throat did something. She managed it.
"Thank you," she said.
She moved back to the front of the column.
---
She found Cal at the midday stop. He'd been huntingâhe and two of Dara's scouts had split from the column and covered the flanking terrain. He came back with two rabbits. Not three, which was what Sable had hoped for, but two was something.
"Better than yesterday," River said.
"Better than yesterday," he agreed. He was field-dressing one of them with the efficiency of someone who'd done this thousands of times. "The terrain's getting different. Less traffic than the lower ground. Animals haven't learned to avoid people as well up here."
"That's good."
"It suggests we're getting farther from the settlements." He glanced north. "Farther from territory anyone's claimed." A pause. "I've been hearing water. Not a streamâsomething larger. Maybe two days north, depending on terrain."
"A river?"
"River or a lake. The sound carries differently at this elevation." He finished the first rabbit. Started the second. "AlsoâI saw something yesterday. When I was on the flank."
"The structure?"
"Not the structure." He was quiet for a moment. "Smoke. Very faint. The kind you'd produce if you were cooking with dry wood and keeping the fire small on purpose. Two miles north."
River went still.
"Someone there," she said.
"Someone who knows enough about fire management to avoid being obvious about it," Cal said. "That's not a refugee campfire. That's the fire of someone who's been doing it long enough to have a method."
"Rider?"
"Too careful for Rider. They don't cook smallâthey cook for a force." He handed her a piece of the cleaned rabbit. She took itâtrail food, requiring fire, but the packs had metal for that. "My best guess is an individual. Someone who's been out here a while."
River thought about that. An individual, two miles north, cooking small fires with method. Out here in high mountain terrain.
"Could be from the structure," she said.
"Could be."
"Or a scout."
"Could be."
She ate the rabbit. Thought.
"Can you get me close enough to see without being seen?" she asked.
He looked at her arm.
"Yes," he said. "If we move tonight, off the column's route, just the two of us."
River considered the cost. One night without both of them at the column. Bernardo for night decisions, Mira for logistics, Dara for securityâthe column was capable without them for one night, as the patrol engagement had proven.
"Tonight," she said. "When the column's settled."
He nodded and went to Sable to deliver the two rabbits.
---
The column made camp in a sheltered bowlâCal's choice, good terrain, three approaches all defensible. The watch was set. Mira had the logistics. Bernardo had the positions. River explained the plan to Dara and Dara received it with the professional acceptance of someone who had expected that sooner or later the two of them would go off and do something like this.
"I'll run the watch," Dara said. "Try to be back before the column moves."
They left at dark. Moving north-northeast, off the main trail, through the forest that Cal read the way River read peopleâthe subtle markers of where the terrain wanted to go, the path of least resistance through ground that didn't have a beaten path.
River moved behind him. QuietâCal's standard for quiet was specific and she'd been practicing it for days, putting her weight where he put his weight, stepping when he stepped, reading his pauses as information about the ground ahead.
Her arm was a low-level problem. Not acuteâthe wound had stopped demanding attention once the fever cleared and settled into the background noise of healing. She kept it close and used it minimally and by the second hour of the night walk it had almost stopped registering.
"Ahead," Cal said, barely above breath. "Left of the big pine. Watch the ground angle."
She watched the ground angle. Adjusted. Three more steps.
The smoke reached her before she saw anythingâold woodsmoke, the cold version that hangs in the air after a fire is damped down. Not fresh. Hours old.
"No fire now," she said.
"Down for the night," Cal confirmed. "We're circling. I want approach from the east."
They circled. Slow, taking thirty minutes to move what would have been ten minutes of walking. The forest thinned slightlyâshe could see sky between the trees, stars.
Then a structure.
Not the large one from Cal's map. This was smallâa single building, stone foundation, heavy timber, the kind of construction people did when they intended to stay somewhere. A lean-to off the south wall. Shuttered windows. A door.
And outside the door, sitting against the wall with their knees up and a crossbow across their lap and their head tilted back, asleepâ
A man. River couldn't see his age from here. Couldn't see his equipment. But the crossbow across his lap was positioned with the ease of someone who slept with weapons available because sleeping without them was something that happened to people in a different kind of world.
"Just the one," Cal said, very quiet.
River watched for ten minutes. Nobody else. No movement from the building. The one person at the door, asleep.
"I want to talk to him," River said.
Cal looked at her.
"He's been here," she said. "He knows this terrain. If the structure you saw is what Vance thinks it isâ"
"If he's alone and been here a while, he might also be protective of his territory." Cal was reading the body language even in sleepâthe weapon placement, the door position. "Or a Rider scout."
"We'll see."
She straightened from the crouch. Stepped forward out of the trees, into the open space around the building, deliberately placing her footfalls just loud enough to register.
The crossbow came up before the man's eyes opened. Fully extended, aimed, no hesitationâthe reflex of someone who'd been woken by sounds before and knew what to do about it.
River stopped. Hands upâleft arm throbbing with the raising, but up. "Not hostile," she said.
The man's eyes opened. Found her. Traced to Cal, who had stepped out of the trees to her right, also hands visible.
He looked at her for a long moment. Then he looked at the arm sling. Then he looked at the machete on her hip and the crossbow on Cal's back.
"How many are you?" he said.
His voice was rough with sleep but under it was something she'd heard in Marcus's voiceâthe flat calibrated tone of someone who'd been doing a serious job for a long time.
"Three hundred and forty-two," she said. "Moving north. Two days behind me."
His eyebrows moved. That, he hadn't expected.
The crossbow lowered a fraction.
"Three hundred and forty-two," he repeated.
"We lost some." She kept her hands up. "My name's River Nakamura-Blake. This is Cal. We're looking for somethingâmaybe you know it. Cascade Station."
The crossbow lowered all the way.
He looked at her with an expression she didn't have a name for. Recognition, maybe, but the kind that makes you doubt what you're recognizing.
"I know Cascade Station," he said. "I've been watching the approaches forâ" He stopped. Recalculated. "Did you say Nakamura-Blake?"
"That's right."
He stared at her. The crossbow went to the ground, propped against the wall. He put his hands on his knees and leaned forward as if the posture would help him see her better in the dark.
"What's your mother's name," he said. "Your mother's first name."
River's chest went cold. Her mother had died when she was seven. She knew the name from her grandmother's stories, said with the specific reverence the dead get when they're beloved.
"Hana," she said.
The man closed his eyes.
When he opened them, they were wet. He didn't try to hide it. He just looked at her with those wet eyes in the dark and said, "I've been here for eleven years waiting to see if someone came."
