From the #1 internationally bestselling author of What Happened to Nina? comes a gripping high-stakes novel of suspense about three seemingly unconnected people, caught in a lethal web of deceit and unhealed wounds. Someone’s watching. Someone’s waiting. Alexis Turner walks into the police station to report an assault. By the end of the day, she is nowhere to be found. Soon after she disappears, three identical packages arrive at three very different doors: a respected psychologist's home, a socialite's mansion, and a struggling single father's run-down apartment. Inside, each gift is perfectly tailored to its recipient — and each will tear apart the life of its intended victim. Detective Sergeant Judith Lee is smart and experienced, but this is no ordinary case. Someone with intimate knowledge of their targets is orchestrating these attacks. Someone who knows exactly how to hurt each victim where they're most vulnerable. As she races to uncover the connection between three unrelated people, Judith discovers she's no longer just investigating the game—she's being forced to play.
