The wind outside the walls was cold enough to hurt — raw, clean air scouring his lungs after years of recycled QZ staleness. It stole the heat straight out of his clothes and Ethan let it, standing still in the rain-shadow of the storm drain, taking the sting of it. He was out. Truly out.
He started walking west before dawn.
The forest took him back the way a language takes back a native speaker. His feet found soft earth without asking; his hands braced on bark he couldn't see; every rustle and crack sorted itself into meaning — wind, animal, wrong. Grandpa Jack's lessons ran underneath all of it, quiet as blood. Don't play their song. Be smarter. Be faster. Be a rock.
Days blurred into weeks. He followed the forgotten animal trails and the land's slow tilt, sleeping in hollows under ancient trees, waking before first light with his hand already on his knife. The MREs were tasteless fuel. Water he found in trickles and dew, cupped in his hands, and it tasted like being alive.
He was fourteen years old, and he walked most of a state on his own two feet.
The infected were everywhere out here — more than he'd ever seen on his QZ runs. Runners shambled through gutted supermarkets with their low, hungry groans. Clickers announced themselves with those hollow clicks that froze him mid-step, breath held, body gone to stone until the sound moved on. On rooftops he lay flat for hours, watching herds move, learning where their ears and noses failed them, filing away which alleys were death and which were merely bad.
One sweltering afternoon, folded into the shadow of an overturned bus with the sun baking the metal over his head, he saw the horde: dozens of Runners and a few Clickers flowing down an old highway like a putrid river. The hum of them vibrated through the bus's skin and into his teeth, a low drone that settled behind his eyes. The air inside the wreck went thick with rot and old heat, sweat running down his back, his palm slick on the knife hilt. He pressed himself into the deepest dark, ribs tight around held breath, and didn't move.
"Too many," he whispered.
He waited out the heat and the stench for hours, counting heartbeats against the metal, until the last of them shambled past. Then he went wide around them, deep into the thick forest where nothing with cordyceps in its skull would bother to follow. His muscles screamed. He thought of Grandpa Jack, and kept walking.
People were worse. He learned to smell woodsmoke from a mile off, to read disturbed earth for pitfall traps, to give spray-painted camp markings a wide berth. One humid evening he found a camp of five scavengers — loud, drunk, no perimeter, arguing over a can of peaches while their fire threw sparks at the sky. He lay in the thicket a long time, watching their discipline rot in real time: no watch rotation, weapons leaning where they'd been dropped, the whiskey bottle making its rounds. Amateurs, and careless with it — the most dangerous kind, because careless people got twitchy.
He could have gone around. But small groups carried things: maps, newspapers, old world scraps that might whisper about the Fireflies or his parents' unit. So he waited until their voices went slack, until the fire burned down to embers and the last argument died mid-sentence. Then he slipped through like weather. He took a folded map from one man's pack and a Firefly flyer from under a sleeping bag, and was gone before the coals cooled.
The map was crude, hand-drawn. But it had the flame symbol — the same one from the QZ propaganda walls — and a line pointing hundreds of miles west, into what used to be Pennsylvania. The flyer was Firefly recruitment: a "safe haven," a "research outpost." A cure, maybe. Answers, definitely. The coordinates were incomplete, but they matched the map's line.
He pushed harder after that. Mountains. Rivers crossed on lashed-together logs. He practiced his knife work on strays, precise and economical, and learned the weight of a pipe, a sharpened stick, a heavy rock. Each day was another refusal to die.
The outpost sat in the ruins of an old industrial complex, brick buildings skeletal against the sky. The closer he got, the quieter it became — a stillness that meant violence had happened here recently and the bodies hadn't finished cooling in anyone's memory. Scorch marks blackened the ground near the gate. Windows hung shattered. A generator still hummed somewhere inside, a heartbeat in the wreckage.
A raid. Fresh — hours, not days. The gunpowder smell hadn't left the air.
He circled the perimeter slow, reading it. Dark stains on the concrete. A drag trail, wide and smeared, running from the main doors toward a loading bay — whoever hit this place had hauled their dead out back. Shattered cameras. Severed wires. No guards, no patrols, no living soul that he could see.
He went in through a ventilation shaft, dropping into an admin building that smelled of old paper and dust. Inside: overturned furniture, scattered equipment, dried blood darkening the concrete in long, dragged smears. No bodies — the drag marks said they'd been taken outside, piled and burned, or piled and taken. Either way, the interior was empty of them, and that was what mattered. His footsteps sounded too loud in the quiet. He kept them small.
He found the data hub three corridors in — old computers, servers still humming, hard copies stacked in ruined order. The power was on. Whoever raided this place had come for blood, not information, and they'd been in a hurry.
Ethan plugged in the little data reader he'd built himself and started the siphon. Nightingale. Immunity. Anomaly. Houston. Parents. His fingers flew across the old keyboard, downloading everything the network would give up.
He was deep into the classified files when he heard it: heavy boots on dry leaves outside. Too few for a patrol. Too quiet for scavengers. Coming in from the west entrance.
His hand closed on the data reader — the little light still blinking, transfer not done — and he snatched up the top stack of physical files. "Non-conversion subjects." The top sheet's header: Patient ID: Subject 38-C. Location: Houston QZ outbreak.
His origin. In his hand.
The boots stopped outside the door.
