Reacher goes where he wants, when he wants. That morning he was heading west, walking under the merciless desert sun, until he comes upon a curious scene. A Jeep has crashed into the only tree for miles around. A woman is slumped over the wheel. Dead? No, nothing is what it seems. The woman is Michaela Fenton, an army veteran turned FBI agent trying to find her twin brother, who might be mixed up with some dangerous people. Most of them would rather die than betray their terrifying leader, who has burrowed his influence deep into the nearby border town, a backwater that has seen better days. The mysterious Dendoncker rules from the shadows, out of sight and under the radar, keeping his dealings in the dark. He would know the fate of Fenton's brother. Reacher is good at finding people who don't want to be found, so he offers to help, despite feeling that Fenton is keeping secrets of her own. But a life hangs in the balance. Maybe more than one. But to bring Dendoncker down will be the riskiest job of Reacher's life. Failure is not an option, because in this kind of game, the loser is always better off dead.
