Detective Eli Mercer is the kind of cop every city wants—disciplined, intelligent, and relentless. After a decorated career built on solving impossible cases, Eli is assigned a volatile new partner, Jax Rowan, a reckless rule-breaker whose instincts are as dangerous as they are effective. The two clash instantly, but together they begin taking down criminals no one else can touch. When a series of murders connected to stolen police evidence rocks the city, Eli and Jax are pulled into a conspiracy that reaches deep into the department. As the case grows darker, Eli begins suffering blackouts, missing hours, and hearing witnesses insist only one detective was ever at the scene. Security footage fails whenever Jax appears, and evidence logs reveal signatures from both men written in the same hand. With Internal Affairs closing in and enemies on every side, Eli turns to police psychologist Dr. Mara Voss to uncover what happened during a failed undercover mission years earlier—the night his mind fractured. Jax is not his partner, but the identity Eli created to survive: fearless, violent, and free from guilt. Now hunted by corrupt officers and a crime syndicate that knows his secret, Eli must confront the two halves of himself before they destroy each other. To expose the truth, he’ll need the control of Eli Mercer… and the chaos of Jax Rowan. In a city built on lies, the only partner he can trust is the one inside him.
