A thrilling read set in the American West from New York Times bestseller C.J. Box, award-winning author of the Joe Pickett and Cassie Dewell series, now adapted into the hit TV shows Joe Pickett and Big Sky. JOE PICKETT IS MADE AN OFFER HE JUST CAN'T REFUSE... Joe Pickett, fired from his job as a Wyoming game warden, receives an unexpected visit from Governor Rulon. The wily governor has a special request, one Joe knows he can't refuse. Lawyer Clay McCann slaughtered four campers in a far-off corner of Yellowstone, then immediately turned himself in. Yet as the crimes were committed on a sliver of land with overlapping jurisdictions, the so-called free-fire zone, nobody can try the worst mass murderer in Wyoming history for his crime. Rulon, aware of the public outrage, will reinstate Joe as a game warden if he'll investigate. Joe, happy to get his badge back even under these circumstances, agrees. With McCann deeply involved with unusually dangerous illegal activity, the key to the murders may be hidden in the rugged terrain of Yellowstone itself.
