Ray Lexmix learned early that the world didn't end with a bang. It ended with a sound — a low, wet tearing noise that you heard in your chest before your ears caught it, like something enormous had taken a bite out of the city and was still chewing.
He was nineteen years old, three weeks past his birthday, and the city of Harlan's Gate was dying.
He didn't run. That was the first thing people always got wrong in the stories they assumed running was the natural response. But running made noise, and noise in Harlan's Gate after dark was an invitation you didn't want to send. So Ray moved the way he always moved: pressed against walls, weight forward on the balls of his feet, breathing through his nose in the long, even pulls his mother had drilled into him when he was seven.
His mother had been smart like that. Had been.
Harlan's Gate had been a fortress city once. Real walls forty feet of reinforced void-null composite steel, built after the Fall of Portland in Year 9. The GDF had stationed two full battalions here. There had been schools, a hospital, three market districts, and on clear days you could see the mountains to the north glowing pink at sunset, and if you squinted you could almost forget what the land between here and those mountains was full of.
That had been eight days ago.
The breach had come from below. Stage 3 Brutes three of them, enough to qualify as a coordinated assault rather than a random surge had tunneled under the eastern wall and collapsed a section of the subsurface drainage infrastructure. The gate teams had scrambled. GDF infantry had poured into the eastern district. And while everyone was looking east, a swarm of ten thousand Stage 1 Hollows had come over the northern wall in the dark, so many of them that the sheer weight of bodies had bent the automated gun emplacements out of alignment.
Eight days later, Harlan's Gate wasn't a fortress city anymore. It was a hunting ground with walls.
Ray was looking for his cousin.
Dayo was fourteen years old, small for his age, and had the extremely specific habit of hiding under the market district when things got bad because the old storage tunnels under the fish stalls were narrow enough that only something human-sized could follow him in, and Hollows Stage 1 Hollows, at least didn't bend well.
Ray knew this because Dayo had survived the Year 31 surge using exactly that strategy. The kid was small and he was smart. Ray was choosing to believe he was still using both of those.
The market district was six blocks north. Six blocks of streets where things moved.
Don't think about them. Think about the route.
He had a knife. It was a good knife his father's, pre-Eclipse design, carbon steel with a textured grip but it was still a knife, and knives against Stage 1 Hollows were functional in the same way that a cup was functional against a flood: technically true, practically insufficient. He also had a modified flare gun that he'd rebuilt with Dayo's help last winter, loaded with two solid-burn rounds that stayed lit for forty seconds each. Hollows were photo-sensitive at the Stage 1 level. Light didn't kill them but it disoriented them enough to matter.
He had not tested this theory against more than six at once.
The street ahead of him was quiet. That was wrong. Harlan's Gate streets were never quiet anymore the Hollows moved constantly, and when they weren't moving you could hear them, the low clicking sound they made in their throats that passed for communication between them. The silence meant one of two things: either nothing was here, or something here was too big to make that noise.
Ray pressed tighter to the wall and waited.
Fifteen seconds. Twenty. Thirty.
Nothing.
He moved.
He found Dayo in the tunnels, exactly where he'd hoped. The boy was huddled in the furthest corner with his knees to his chest and his eyes so wide they were mostly white, and when Ray ducked through the entrance and said his name quietly, Dayo made a sound like a pressurized canister releasing.
"Ray. Ray. It's you. I thought you were"
"I know what you thought. You're okay."
"I'm not okay. I've been in here for two days. There was a Stage 3 on the street above this morning. I could feel it through the floor. The floor was shaking, Ray."
Ray looked at his cousin. At the dark circles under his eyes and the shallow, too-fast breathing and the way he was holding his own arms like they might float away.
"Can you walk?"
"Yes."
"Can you walk quietly?"
A pause. Dayo's breathing steadied by a fraction.
"Yes."
"Then we're going to the GDF eastern rally point. There's still a unit operating out of the old processing plant on Ninth. I know the route."
"How do you know?"
"I've been watching them for two days."
Dayo stared at him. He had the same eyes as Ray's mother big, dark, and capable of carrying a question and a judgment at the same time.
"What were you doing for two days before that?"
Ray picked up Dayo's pack from the corner. He handed it to him.
"Looking for you. Let's go."
They were four blocks from the processing plant when the Striker came.
Stage 4. Ray had never been within visual range of one before. He'd seen the aftermath the scored walls, the structural damage, the specific pattern of destruction that Striker tails left when they swept through enclosed spaces but he had not seen one.
It dropped from the roof of the building across the street without a sound and stood in the middle of the road with its head tilted at an angle that no human neck could manage, and it looked at them.
Dayo made no sound. Ray gave him credit for that.
The Striker was tall taller than the GDF intel descriptions had suggested with limbs that were slightly too long and skin the color of deep water, and the tail had a curve to it that reminded Ray of a question mark. Its eyes had no iris, just a wash of silver from edge to edge. It was looking at them the way a person looks at something interesting rather than the way an animal looks at prey.
That was the most terrifying part. The interest.
It took one step toward them.
Ray raised the flare gun.
He didn't think about it. Didn't calculate. His arm came up, his thumb cocked the round, and he fired not at the Striker but at the ground directly beneath it, where the solid-burn round impacted the cracked asphalt and ignited into a column of white-hot sustained light three feet from the creature's feet.
The Striker screamed. It was not a sound Ray had heard before or would forget after not animal, not mechanical, something in between, something that felt wrong in the frequencies a human throat could produce. It lunged backward and up simultaneously, its tail whipping for balance, and vanished over the rooftop in a single motion that shouldn't have been physically possible.
Gone.
Forty seconds of light. Then the flare died.
Ray's hand was shaking. He noticed it the way you notice a strange sound in a wall academically, at a slight remove.
"...That was a Stage 4."
"Yes."
"You scared off a Stage 4 with a flare gun."
"Temporarily."
"How long do we have?"
"Until it figures out that the light is gone. Walk fast."
