At twenty-four, Y/N thought becoming a detective would mean chasing criminals and proving herself in a department that already doubts her. Instead, she’s thrown onto the city’s most infamous unsolved case: a trio of vigilante serial killers who target people the justice system failed to punish. Kieran Vale, Dante Mercer, and Ryker Sloane are intelligent, ruthless, and impossible to catch—but the closer Y/N gets to uncovering who they are, the more dangerous the line between hunter and hunted becomes. With her charming partner Cameron Hayes determined to protect her and the three killers becoming increasingly obsessed with the detective investigating them, Y/N finds herself trapped between justice and something far darker. Because the deeper she digs into their crimes, the more she starts to wonder if the monsters she’s chasing might actually be the only men telling the truth.
