Synopsis

Neon hangs inside an underground dome: Eden glittering at the bottom where it's the safest, the Casuals grinding in the middle, the Harbor and Penumbra rotting up above in the forgotten parts. Information is currency. Memory can be stolen. Consciousness is something corporations have learned to bottle.

Yeji runs data for whoever pays, and for the one person she still has left. When a Harbor king hands her a spider meant for Mantis Corp's mainframe, she takes the job knowing it will put a target on her back.

Vincent Campbell is a veteran cop, a detective whose job it is to walk through other people's minds. A jumper, a locked mnemonic, and a whisper of "errorists" pull him off the official map and toward a runner he already doesn't trust.

Ashley is Mantis Corp's prototype: an android paramedic built to save lives, reset nightly, and never ask why. She wakes in a body bag among the city's scrap-hunters and chooses, for the first time, not to go home.

Their paths knot around a corporation that wants more than labor from the people it claims to serve, and around the question the city has been avoiding: if a mind can be copied, sold, or overwritten, what is left that still belongs to you?

A cyberpunk noir about loyalty, stolen selves, and the cost of leaving the door unlocked.

It wasn't the first time I had woken up in a body bag, but this might be the last. Especially because I wasn't where I was supposed to be: at Mantis Corp.

The lights were so bright it felt as if I was staring directly into the sun. A Human would probably evacuate their stomach contents by now. For me, it was just an analysis.

I ran a diagnostic. Then I remembered who did this.
