The FBI has a secret weapon. But now the secret's out.

When missing teens begin turning up dead in a small Southern town, the FBI sends in Special Agent Samantha Cash. Her methods are invisible, and she never quits until a case is closed.

Homicide detective Connor Wolfe is running out of ideas--and time. His relationship with his headstrong daughter is in a tailspin, and the string of unsolved murders has the town demanding answers.

When Samantha joins Connor in a race against the clock to stop the killer, things start to get personal. If they're not careful, someone close to them may end up the next victim.
