“[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.
