Atlanta, 1974: As a brutal murder and a furious manhunt rock the city's police department, Kate Murphy wonders if her first day on the job will also be her last. She's determined to defy her privileged background by making her own way--wearing a badge and carrying a gun. But for a beautiful young woman, life will be anything but easy in the macho world of the Atlanta PD, where even the female cops have little mercy for rookies. It's also the worst day possible to start given that a beloved cop has been gunned down, his brothers in blue are out for blood, and the city is on the edge of war. Kate isn't the only woman on the force who's feeling the heat. Maggie Lawson followed her uncle and brother into the ranks to prove her worth in their cynical eyes. When she and Kate, her new partner, are pushed out of the citywide search for a cop killer, their fury, pain, and pride finally reach the boiling point. With a killer poised to strike again, they will pursue their own line of investigation, risking everything as they venture into the city's darkest heart.
