As darkness closes in on the city of shattered light, an heiress and an outlaw must decide whether to fend for themselves or fight for each other. As heiress to a powerful tech empire, seventeen-year-old Asa Almeida strives to prove she's more than her manipulative father's shadow. But when he uploads her rebellious sisters mind to an experimental brain, Asa will do anything to save her sister from reprogramming--including fleeing her predetermined future with her sisters digitized mind in tow. With a bounty on her head and a rogue AI hunting her, Asas getaway ship crash-lands in the worst possible place: the neon-drenched outlaw paradise, Requiem. Gunslinging smuggler Riven Hawthorne is determined to claw her way up Requiems underworld hierarchy. A runaway rich girl is exactly the bounty Riven needs--until a nasty computer virus spreads in Asas wake, causing a citywide blackout and tech quarantine. To get the payout for Asa and save Requiem from the monster in its circuits, Riven must team up with her captive. Riven breaks skulls the way Asa breaks circuits, but their opponent is unlike anything theyve ever seen. The AI exploits the girls darkest memories and deepest secrets, threatening to shatter the fragile alliance theyre both depending on. As one of Requiems 154-hour nights grows darker, the girls must decide whether to fend for themselves or fight for each other before Rivens city and Asas sister are snuffed out forever.
