"[Lisa] Gardner keeps us guessing till the end!"--Los Angeles Times

Death always strikes on time.

Each time he strikes, he takes two victims. He waits for the first victim to be discovered--a body containing all the clues investigators need to find the second victim, who counts the seconds to a slow but certain death.

Now two girls have disappeared and the deadly countdown begins again. Rookie FBI agent Kimberly Quincy knows that the killer's deadline can be met--but she'll have to break some rules to do it. Joining forces with her father, renowned FBI profiler Pierce Quincy, and his partner, Rainie Conner, Kimberly will begin a dangerous hunt for a predator like none she's ever seen.

He's had five years to perfect his game. Now the clock is ticking. For his victims and for Kimberly . . .

Time's up.
