Wolf pack

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 grandson 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 have arrived. Their target seems to be the mystery man and everyone--including Joe Nate and others--who are 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.
