6 teenage girls have been kidnapped, brutalized, and murdered in the Washington DC area and the FBI's SPCD Unit - the Sexual Predators of Children Profilers - are nowhere close to finding the monster responsible. How are the victims chosen? How does the killer find them, contact them, lure them into his sick web? Questions the team has no answers for. When a high-ranking US Senator's daughter is the next victim, SPCD team leader, Tucker Petrie, is forced to call upon retired profiler -- and his last partner -- Kella O'Brien for help. Kella's been out of the game for 10 years, but her expertise and insights into a serial killer's mind are unparalleled. If anyone can discover who this madman is, it's Kella. But as the team rushes to prevent another young girl's death, clues the killer leaves behind have Kella wondering if his endgame is all about...her.
