Six girls missing . . . and every clue leads to a dead end

During Garrett Addison's first week on the job as a criminal investigator for the Tennessee Bureau of Investigation, his team is called out to a murder scene of a young girl. She's just one in a string of disappearances with one thing in common--a Polaroid photo of each victim left behind at the crime scene.

The FBI is pulled into the case to help, and Garrett finds himself working with Special Agent Jordan Lambert, the woman he once loved. When yet another girl dies, Garrett wonders whether he really has what it takes to be an agent. Maybe he should just walk. But while he may be done with the killer, the killer is not done with him--or Jordan.
