"Some monsters are built. Some are born. And some... are programmed." Koa Onyx Rhodes-known in the underworld only as Zero-is the faceless queen of The Grid, a cyber mafia empire that controls the black market, digital extortion, and money laundering for every major crime syndicate in the world. Ruthless, untouchable, and cloaked behind firewalls and shadows, Koa hasn't let anyone close in nearly a decade-not since the night she killed the man she loved. She doesn't trust. She doesn't forgive. And she doesn't make mistakes. Until Cassian Devereux crashes into her world. Cassian is a mechanic with grease under his nails, drowning in the debt left behind by his gambling-addicted father. He's spent his whole life holding his broken family together-but when his father crosses The Grid, money isn't enough. The Grid wants something else. Him. A year of servitude to wipe the slate clean. Cassian steps into her cage thinking he's just a pawn. A name on a contract. A means to an end. But the longer he's forced to work under Zero's rule-running errands, cleaning up digital messes, and navigating her deadly empire-the clearer it becomes that the real danger isn't her threats... It's her. She's not just a criminal. She's a mystery wrapped in scars, silence, and broken code. And the more he unravels her, the harder it becomes to walk away. In a world of secrets, power plays, and ghosts from the past, one question remains: When you decode the monster... what do you do when you realize she's the only thing you don't want to survive without?
