Tomás Cruz swore he would never be like his father, an abusive cocaine junkie whose gangland exploits are notorious throughout the underbelly of northern Argentina. When Samuel Cruz is sentenced to thirteen years in prison, he leaves a laundry list of unfinished cartel business. Seba, Tomás's revered older brother, has no choice but to abandon his straight life and take over his father's underworld debt. Now fifteen years have passed, Seba has been arrested, and the ruthless cartel boss is holding his wife and daughter as collateral—just in time for the holidays. Tomás is forced to choose between protecting his family and his soul as he assumes the to-do list where Seba left off, plunging into the shocking depravity of the cartel to track a drug deal gone wrong. On a bloody quest for underworld justice that takes him from a sex-trafficking bar to the murky depths of the Paraná River, Tomás discovers himself capable of violence he never thought possible. He must ask himself if he really is his father's son ... and he may not like the answer.
