UNSOLVABLE MATH

The end of the world didn't smell like fire or brimstone. It smelled like scorched rubber, stale adrenaline, and the wet copper tang of a slaughterhouse that had forgotten to close its doors.

"Jason, please!"

I played the desperate girlfriend well. I let my voice go thin, the sound of a woman who still believed a man's name was a safe place to store her heart. I struck the SUV's window with both palms, leaving oily smears that looked exactly like panic.

Jason didn't look at my face. He was too busy shoving a crate of my water, bought with six months of emergency funds, into the back seat.

Cami sat in the passenger seat, staring straight ahead like she could delete me by refusing to look. Three years I'd called her my best friend. Three years I'd covered her rent when her shifts got cut.

"There isn't room, Audrey!" Jason's voice cracked, jagged with his own cowardice. He wasn't looking at my eyes. He was looking at my throat, the way an appraiser looks at jewelry he's already priced as scrap. "The weight, the fuel, we have to think about the future. Three people is just math we can't solve."

"I bought the fuel, Jason. I found the keys."

I reached for the door handle. He was faster. He pried my fingers off it, one by one, with a clinical coldness that made the horde behind me feel warm by comparison. Then he shoved me, and I hit the asphalt hard enough to feel it in my teeth.

I didn't scream. I didn't beg. I watched the taillights vanish into gray, soot heavy fog, and I filed it. Jason. Cami. The five hundred dollars. The stolen water. The way he didn't blink when my head hit the road.

The first shadow fell over me. It wasn't the shadow of a man. It was rotting, gray, and driven by a hunger so complete it had become a personality.

I stayed on my hands and knees and waited.

When the teeth found my throat, the world didn't go black. It went white.

[LUS SYSTEM INITIALIZING.] [HOST VITALITY: 0.01%. ERROR.] [REVERSING ENTROPY. RECALIBRATING TIMELINE TO POINT ALPHA.] [APEX EVOLUTION: ACTIVE.]

I woke to the sound of my own lungs.

My fingers went to my neck, scraping bare, unmarred skin instead of torn muscle. For one sick second I couldn't remember why that was wrong. Only that it was.

Dead. I'm dead. This is what dead feels like.

But my hair hung heavy against my neck instead of drifting in some current, and gravity held me flat to the mattress. Not the Abyss. Not the wreck of the 4th Street intersection.

Sunlight cut gold bars across the rug. Cotton sheets under my palms, not asphalt. I understood, with the clarity that comes right before panic, that I was standing on ground a dead woman had no business touching.

I was back.

Lavender detergent. The sugared smell of peaches I'd bought yesterday. Yesterday, forty-eight hours before the first Grey S. case hit the news.

My phone buzzed on the nightstand, a hum I felt in my teeth.

Jason: Hey babe, can I borrow $500? Car repair's more than the guy quoted. Stuck at the shop. Love you!

"Love you" sat at the end of that message like a debt collector's receipt.

My hand hovered over the screen. Not shaking. My heart slammed against my ribs, but it wasn't the frantic thrum of the girl who died in the street. It was denser. Deliberate. A rhythm coming from somewhere behind my sternum that wasn't entirely mine.

[Welcome, Host.]

The voice didn't arrive through my ears. It started in my marrow and climbed until it found the back of my teeth, patient as the tide dragging stones under. [Level Up System online. Transition is usually crueler for your kind. You were already halfway to being one of ours.]

"What are you?" I whispered. My voice came out a fraction of its normal size.

[I am your leash. And I am your life. You crossed the shelf line asking to be found, Audrey. Now you find a way to make it worth the debt. The interest is already rising.]

I looked at my reflection in the dark phone screen. My eyes had dimmed at the edges, brown bleeding into a smoky, glassy gray that wasn't a color so much as an absence of light.

I looked like something the system had finished remaking.

I picked the phone back up. My fingers were perfectly steady. The trembling woman who had begged Jason for a seat in a car that wasn't his was a costume, and I folded her away neatly, somewhere I could find her again if I ever needed to wear her.

I started typing.

Me: Of course, Jason. Come over. Cami too. I've got cash in the safe. We should talk about the future.

Send.

File it, I told myself. The betrayal. The hunger. The math of who gets to live.

[Mission Assigned: Reclaim Assets.] [Reward: 5 Strength Points. 1 Predator's Mark.] [Note: Hunger is a personality, Host. Don't let yours go hungry.]

Forty-eight hours. That was all I had before the city's lungs started failing one block at a time, before the world outside my window turned into the one I'd already died in once. Forty-eight hours to turn this apartment into a tomb for the woman who begged and a fortress for the one who wouldn't have to again.

I walked to the kitchen and picked up a knife. In the morning light it didn't look like steel. It looked like a shard of something older, black and watching.

I wasn't a girl anymore. I was an investment, and interest was already accruing on every person who had ever decided I was worth less than the space I took up in a car.

Jason wanted five hundred dollars.

He had no idea what the exchange rate was about to become.

I texted one more line before I set the phone down.

Me: Bring Cami. I mean it. There's room for everyone this time.

Somewhere out there, men who didn't know my name yet were about to start sending invitations of their own. Generous ones. The kind that came wrapped in flowers and ended in debt.

I had died once already for believing a man's math. I wasn't going to do the arithmetic that way again.

I opened the door to let the last ordinary morning of my old life walk in, one last time, so I could watch exactly how it died.
