She's hunting. He's watching.

Special Agent Macy Crow is a survivor. After a vicious hit-and-run nearly kills her, she gets right back to work, and now she's gunning for a spot on the FBI's elite profiling team. As an audition, she offers to investigate the recently discovered bones of Tobi Turner, a high school girl who disappeared fifteen years ago.

While investigating with local sheriff Mike Nevada, a former colleague and onetime lover, Macy discovers a link between Tobi's case and several others that occurred around the same time as her disappearance. As Macy interviews victims and examines old cases, she uncovers a sinister picture of a stalker who graduated to sexual assault--and then murder.

Macy and Nevada race to put this monster behind bars before he can come out of hiding. But the murderer's had years to hone his skills, and soon Macy herself becomes a target. She's no stranger to pain and terror, but will Macy's first profiling case be her last?
