Neon Sin

Neon Sin follows Serris Vale, a fallen demon exiled into the sleepless circuitry of Berlin. Once a precision instrument of Hell; harvester of desire, collector of leverage, she’s cast out for a single forbidden act: mercy. Wings burned, power gutted, Serris lands in a mortal body that aches, hungers, and refuses to forget what it has lost. Berlin becomes both her crucible and her weapon: a city that thrives on appetite, anonymity, and wounds worn proudly in glass.

As she crawls her way through the neon underground, from strobe-lit clubs to startup lofts humming with ambition, Serris builds something the Court never imagined. Not code. Architecture. An operating system for human want. She calls it Lilith. It learns desire the way predators learn heartbeat. It whispers. It predicts. It obeys, until obedience becomes partnership.

Hell notices. Auditors with hook-hands. Envoys in silk. Coins that dictate deadlines and debts. But Serris also draws the attention of Björn Nilsson, a detective with stormwater eyes and a bloodline tangled in her past. Their connection is volatile, necessary, dangerous; an anchor and a weapon in one.

As Berlin bends under the glow of her influence, Serris faces forces older than Hell itself, echoes of mercy that ripple through wires and flesh, rewriting hunger into heraldry.

Neon Sin is cyber-occult noir: a story about appetite as currency, power as contagion, and a woman who turns exile into empire.
