Once a small town girl, Detective Kat Gonzales is now the only female detective in the Corpus Christi Police Department. Her colleagues mostly ignore her. Being overlooked can be helpful when she wants to break the rules, but she's tired of struggling for respect. She's a good cop who wants recognition for doing her job as well as-or better than-the men. When the wife of Kat's boss is murdered, he is investigated as the prime suspect. Shortly after the investigation begins, two fellow officers were murdered. The crimes rock the department, but Kat manages to stay out of the fray as one of the few officers still carrying out their normal duties. As the murder of her boss's wife remains unsolved, a rash of homicides throughout Corpus Christi raises alarms. Kat works alongside two Texas Rangers brought in to help stop the bloodshed. They think they might be getting close ... until a shocking twist propels Kat into a wild investigation filled with danger, death, and suspicion. She wanted to be one of the boys; now, she just wants to stay alive.
