Chapter 1: The Sky Diagnosed Us

Mara Voss was elbow-deep in a dying man’s chest when the sky asked humanity to choose a difficulty.

The man on Trauma Two’s table had no name yet. Just a body on a red-slicked sheet, a leather jacket cut open to the armpits, ribs cracked beneath Mara’s forearm, and a heart that kept trying to quit under her gloved fingers.

“He’s losing pulse again,” Dr. Eddings snapped.

“He never got it back,” Mara said.

Her hand was inside him, wrist buried past the ragged mouth the thoracotomy had made. His blood was hot at first, almost scalding, then cooling too fast as it flooded around her fingers. The overhead surgical lamps buzzed white. The trauma bay stank of copper, cautery smoke, betadine, sweat, and cheap whiskey leaking from the patient’s breath. Somewhere behind her, a woman screamed for someone named Mateo. Somewhere beyond that, Cleveland groaned under another night of sirens.

“Cross-clamp,” Eddings said.

“You already clamped,” Mara said. “Aorta’s a wet noodle. He’s shredded.”

“Then massage harder.”

Mara curled her palm around the dying man’s heart and squeezed.

Once. Twice.

It fluttered like a trapped bird.

The monitor answered with a flat, obscene tone.

“Come on,” she muttered, not to God, not anymore. “Don’t make me waste the paperwork.”

Jules, the night charge nurse, barked a laugh that was half hysteria. “That’s the bedside manner we’re famous for.”

The lights flickered.

Every screen in the trauma bay went black.

For one impossible second, the hospital fell silent—not quiet, never quiet, but silent in the way a battlefield became silent between the whistle and impact of a shell. No monitors. No ventilators cycling. No pump alarms. No fluorescent hum. Just breathing, dripping blood, the distant animal murmur of too many frightened people packed behind curtains.

Then the sky spoke.

It did not come through speakers. It did not echo from the ceiling. It arrived inside Mara’s skull with the clean, merciless weight of a diagnosis stamped across a chart.

Choice window: 00:00:10

Mara’s grip tightened around the dying man’s heart.

“What the hell was that?” Jules whispered.

The black monitors reflected faces turned upward, eyes wide. Dr. Eddings stood frozen with his clamps in one bloody fist. A surgical resident crossed himself. The patient on the table gave a wet, impossible gasp despite the fact that his chest was open and his heart sat in Mara’s hand.

Beyond the narrow slit of the trauma bay doors, people began to shout.

“You all saw that?” Eddings said.

“Saw?” Mara asked.

The world answered before anyone else could.

The dark windows above the ambulance bay bloomed white.

Not lightning. Not explosion. The night sky over Cleveland split from horizon to horizon, opening along a seam no cloud had hidden. Through the glass, Mara saw a vertical wound of silver-blue fire carve itself between the high-rises, pouring light down onto Euclid Avenue and the frozen ambulances at the curb. Snow—or ash, or something fine and luminous—drifted upward instead of down.

Patients screamed.

The ten-second timer ticked inside Mara’s vision.

00:00:07

“Don’t choose anything,” Jules said. Her voice had gone small. “Nobody touch anything.”

“It’s in my head,” a resident sobbed. “It’s asking—why is it asking?”

00:00:05

Mara thought of her brother in Oncology on the eighth floor, lungs filling cell by cell with a cancer too stubborn to name anything but inevitable. Owen, twenty-seven, all elbows and bad jokes, sleeping under a Cleveland Browns blanket like spite could bully death into giving him another season.

Mercy, some terrified animal part of her begged.

But Mara had learned about mercy in Helmand, when a boy missing both legs asked if his mother was coming and all she could do was hold pressure until his eyes stopped tracking hers. Mercy was what people named the knife when they wanted you to thank them for the cut.

00:00:03

A sound rose outside. Hundreds of voices, maybe thousands, shouting different choices to an indifferent sky.

“Mara,” Jules said. “What do we pick?”

Mara squeezed the heart again. It did not answer.

“The one that keeps people alive,” she said.

She didn’t know which one that was.

00:00:00

NO CONSENSUS DETECTED.

Regional Difficulty determined by aggregate fear response, population density, local trauma index, and buried anomaly proximity.

CLEVELAND NODE 7-C DIFFICULTY: ASCENDANT

The hospital exhaled.

Then everything broke.

Power slammed back in a stuttering surge. Lights exploded overhead, raining sparks across tile. The ventilator in Trauma One screamed and died. Every phone in the room shrieked emergency alerts at once, the tones overlapping until they became one metallic howl. Somewhere deep below, something boomed against the bones of the building hard enough to make the floor jump beneath Mara’s boots.

The nameless man on the table opened his eyes.

They were no longer brown.

They were white, filmed over like boiled eggs, and full of writhing black threads.

“Nope,” Mara said.

His heart convulsed in her hand.

Ribs cracked inward. Not from her. From him.

His broken sternum knitted wrong in a rapid series of wet pops, bone hooks curling up like fingers around Mara’s forearm. The corpse—or whatever had borrowed it—smiled with a mouth full of blood foam.

“Get her out!” Jules shouted.

Mara yanked her arm free as the chest cavity snapped shut. Bone teeth scraped her glove, tore through nitrile, and scored white-hot lines across her skin. She stumbled back into an instrument tray. Scalpels and clamps cascaded to the floor.

The patient sat up.

Eddings hit him with the defibrillator paddles on instinct. “Clear!”

The shock snapped through the body. The man’s back arched. For a heartbeat, smoke curled from his chest.

Then he laughed.

It was not a human laugh. It was five laughs braided together, deep and childish and choking and delighted.

He lunged across the table and bit Eddings in the face.

Cartilage crunched.

Blood sprayed across Mara’s visor.

Jules drove a trauma shear into the thing’s neck, both hands on the handle, face twisted with rage. “Let go of him!”

The thing turned its milk-white eyes toward her. The shears quivered in its throat.

Mara grabbed the oxygen tank from beside the wall, swung it like a battering ram, and smashed it into the patient’s skull. Once. Twice. The third blow caved in the temple with a sound like a melon dropped from a roof. It toppled off Eddings and hit the floor twitching.

For two seconds, nobody moved.

Then the body began dragging itself toward the nearest curtain with one shattered arm.

“Restraints,” Eddings gargled from the floor, half his cheek hanging open.

Mara looked at him. Looked at the crawling thing. Looked at the bite mark already darkening along his jaw, black veins spreading beneath his skin.

“Mara,” Jules said, very quietly.

They had both seen enough people die to recognize the arithmetic. Sometimes survival was not a rescue. Sometimes it was subtraction.

Eddings tried to speak. His tongue looked wrong. Too long. Splitting at the tip.

Mara seized a fallen scalpel.

The bitten doctor stared up at her, one eye full of blood, one eye full of fear. “Don’t,” he said. Or tried to.

The thing that had been their patient reached the curtain. Behind it, a teenage girl with a broken arm began to scream.

Mara crossed the distance in three strides and drove the oxygen tank down on the corpse’s skull until it stopped moving.

A translucent message snapped into the air over the body.

Hostile neutralized.

“I’m hallucinating,” Jules said.

“Later,” Mara said.

Dr. Eddings made a wet clicking sound.

Mara turned.

His body was seizing, heels drumming against tile. His fingers clawed at his own throat. The black veins had crawled from the bite across his face and down under his collar, spreading like spilled ink in water. His mouth opened too wide. Teeth loosened, then sharpened, pushing outward through bleeding gums.

Jules backed into the crash cart. “David. David, listen to me.”

Eddings’ eyes rolled toward Mara.

For one second, he was still there. A tired ER surgeon with three divorces, bad coffee breath, and a photo of his golden retriever taped inside his locker. Then something behind his face looked out and found the room full of meat.

“Move,” Mara said.

Jules didn’t.

Eddings sprang.

Mara tackled Jules aside as he hit the crash cart. Metal screamed. Drawers burst open. Syringes skittered across the floor like insects. The doctor landed on all fours, spine humping upward beneath his scrub top, bones shifting with fast, nauseating certainty.

The teenage girl behind the curtain sobbed, “Mom, I want my mom.”

“Everybody out!” Mara shouted. “Move to the hall! Now!”

“The hall’s worse!” someone yelled back.

He was right.

The ER beyond Trauma Two had become a butchered hive.

Doors banged. People shoved gurneys into barricades. A man in a hospital gown stood in the center of the nurses’ station with his head bent backward until his skull rested between his shoulder blades, laughing at the ceiling while his fingers split into too many joints. A security guard fired his pistol into a crawling patient whose abdomen had peeled open like a flower, each petal lined with wet teeth. The bullets punched holes, but the patient kept dragging herself forward, whispering, “Hungry, hungry, hungry,” in the voice of a little old woman.

Above it all, the System kept speaking.

Welcome, Probationary Species.

Your world has failed quarantine integrity.

Existing civil structures have been designated Transitional Arenas.

Survive. Adapt. Ascend.

Initial Class Selection available upon qualifying event.

Mara felt laughter trying to crawl up her throat. It came out as a snarl.

“Of course,” she said. “Of course it’s a tutorial.”

Eddings launched at her.

Jules hit him with a fire extinguisher.

Foam burst across his face. Mara grabbed a heavy stainless suction canister and smashed it into his knee. The joint inverted. He fell, snapping at her boot. She kicked him under the jaw hard enough to crack teeth.

“We need to get upstairs,” Mara said.

Jules stared at her. “Upstairs? The whole hospital’s turning into a blender and you want a change of scenery?”

“Owen’s on eight.”

The fear in Jules’ face shifted shape. Not less fear. A different kind. Human. Anchored.

“Oncology,” she said.

“Yes.”

Jules looked toward the ER doors, where something huge slammed into the ambulance entrance hard enough to spiderweb the reinforced glass. A silhouette crouched outside in the glare of burning vehicles, too tall, shoulders brushing the top of the entryway. Antlers—or exposed ribs, or a crown of bone—scraped the metal frame.

“Stairs,” Jules said. “Elevators are dead.”

“You don’t have to come.”

Jules snatched a roll of tape, wrapped it around the fire extinguisher handle for grip, and gave Mara a look sharp enough to cut. “If I die because of your brother, I’m haunting your ass.”

Mara almost smiled.

Then the thing outside hit the doors again.

The glass blew inward.

Cold night air and burning gasoline flooded the ER.

The creature that squeezed through had once maybe been a deer, if a deer had been assembled by someone who hated deer and misunderstood mercy. Its front legs were too long, ending in hands with black nails. Its hide hung in translucent sheets over a cage of exposed ribs. Human faces pushed from its flanks, cheekbones stretching the skin, mouths opening and closing without sound. Antlers rose from its skull in a tangled rack of IV poles, bone, and rebar.
