Wyoming game warden Joe Pickett encounters bad behavior on his own turf--only to have the FBI and the DOJ ask him to stand down--in the thrilling new novel from #1 New York Times-bestselling author C.J. Box. The good news is that Joe Pickett has his job back, after his last adventure in The Disappeared. The bad news is that he´s come to learn that a drone is killing wildlife--and the drone belongs to a mysterious and wealthy man whose son is dating Joe´s own daughter, Lucy. When Joe tries to lay down the rules for the drone operator, he´s asked by the FBI and the DOJ to stand down, which only makes him more suspicious. Meanwhile, bodies are piling up in and around Joe´s district in shocking numbers. He begins to fear that a pack of four vicious killers working on behalf of the Sinaloa cartel known as the Wolf Pack has arrived. Their target seems to be the mystery man and everyone--including Joe, Nate, and others--who is associated with him. Teaming up with a female game warden (based on a real person, one of the few female game wardens at work in Wyoming today) to confront these assassins, Joe finds himself in the most violent and dangerous predicament he´s ever faced.
