Prologue

Outpost Erebus — Final Sunset

The corpse in Cold Room Three is still trying to find warmth.

Its fingers scrape the inside of the specimen drawer with a slow metallic rhythm: four scratches, silence, four scratches. The shifter died eleven hours ago. I signed the certificate myself after the White Hunger stopped his heart and turned his blood the color of skimmed ice.

Dead things should not shiver.

I stand behind the safety glass with one hand on the freezer controls and watch frost pulse beneath the body’s skin. It gathers along the veins, retreats, then gathers again as though something inside him is breathing through the cold.

"Record time," I say.

The laboratory system answers in its pleasant corporate voice. "Sixteen forty-two, local. Solar disappearance in eighteen minutes."

Eighteen minutes until the last rim of sun drops below the Arctic horizon. Eighteen minutes until Outpost Erebus begins sixty days of polar night.

The dead man’s eyes open.

I hit the emergency freeze. Liquid nitrogen screams through the drawer housing. The thing inside throws itself upward hard enough to bow reinforced steel, its jaw snapping at heat it cannot see. A sound comes from its throat—not a growl, not speech, but hundreds of overlapping whines compressed into one starving note.

My wolf recoils beneath my skin.

Then every monitor in the room flashes white.

BIOLOGICAL ANOMALY CONTAINED.

APEX BIOLOGICS THANKS YOU FOR PROTECTING TOMORROW.

The message appears before the body has stopped moving.

I stare at it until my breath fogs the glass. "Delete the slogan. Preserve the raw feed."

"Raw feed requires executive authorization."

"Authorization Mercer-seven-black."

A pause. "Credential restricted."

Restricted. Not expired. Someone above me changed my access while I was in the room.

I pull the recorder chip from the wall before the system can wipe it. The plastic bites into my palm. On the other side of the glass, the corpse’s fingers slow. Four scratches. Silence. Four scratches.

The pattern matches the distress signal from North Pack Seven, the settlement my failed vaccine was supposed to protect.

Forty-three infected. Forty-three names attached to the decision that follows me into every sterile room.

The intercom clicks.

"Dr. Mercer, report to Sublevel Nine for the Eclipse specimen’s final draw."

Specimen.

His name is Varek Nyström. Thirty-seven years old. Former rescue commander. Eclipse-born vampire-wolf hybrid. Apex has kept him three hundred feet beneath the ice for nineteen months because his blood kills the White Hunger in a dish.

It also kills every pure vampire cell it touches.

I know that result. I ran it twice, then hid the second set because the research director smiled when he saw the first.

"Final draw for what protocol?" I ask.

Only static answers.

The laboratory door unlocks behind me. Director Hale enters in a white parka he does not need indoors, flanked by two security officers carrying silver inhibitor rifles.

"The sun is setting," he says. "His vampiric expression will strengthen. We need a complete dark-cycle baseline before transfer."

"What transfer?"

"You don’t have clearance."

"I had clearance an hour ago."

His eyes move to my closed fist. "What did you remove from the system?"

I let my claws press just far enough into the recorder chip to crack its casing. "A contaminated disposal tag."

He smiles without warmth. "Your attachment to failed subjects remains your least scientific quality."

My wolf pushes against my ribs. I force my hand open before he sees blood. "The dead shifter in that drawer synchronized with North Pack Seven after cardiac death. The infection is forming a network. If polar night amplifies it—"

"Then Varek’s antibodies become more valuable."

Not the patients. The antibodies.

I look past Hale to the corridor window. The sky is a narrowing band of bruised gold over endless white. Somewhere far across the ice, shapes move between the station lights. Too many to be caribou. Too coordinated to be wind.

"The surface patrol should come inside," I say.

"They have orders."

"Whose?"

Hale steps closer. His voice drops. "Draw the blood, Doctor. Keep the hybrid calm. When the transport arrives, your part in this project ends cleanly."

The threat is almost gentle.

I slide the cracked chip into my sleeve and walk past him.

At the elevator, my badge no longer opens any level above the laboratory. It opens only Sublevel Nine. The doors close, trapping me with my reflection: silver beginning to rim my irises, a wolf-shifter in a white coat pretending the corporation owns only her credentials.

As the car descends, I remove a steel cylinder from the emergency panel. Every station buried this deep has a self-freeze protocol. Turn the key, enter the director’s code, and cryogenic failsafes lock the core in a block of engineered permafrost. No evidence leaves. No living thing does either.

The code cylinder should be sealed.

It opens in my hand.

Inside, on a strip of paper, someone has written five words.

ASK VAREK WHO BUILT THE PLAGUE.

The elevator lights flicker.

Above me, an alarm begins and stops so quickly it could be imagination. My radio catches half a scream from the surface patrol. Then the station announces sunset.

Darkness drops over Erebus like a lid.

From somewhere inside the walls comes the same sound as the corpse: four scratches, silence, four scratches. Closer now. Moving downward.

The elevator opens onto Varek’s corridor.

Silver cuffs wait on the chair. A fresh blood vial waits on the tray. Behind reinforced glass, the Eclipse-born hybrid raises his head before I take a single step, as if he has been listening to my pulse through nine floors of ice.

His eyes are already black with night.

"Dr. Mercer," he says through the speaker. "You finally heard them."

"Heard what?"

Varek looks toward the ceiling.

The scratching begins again.

"The dead pack," he says. "They’re coming home."
