In this historical Western by the New York Times –bestselling authors, the legendary sheriff of Tombstone, Arizona, faces the fight of his life. Tombstone, Arizona, is the most violent town in the west. But now the legendary frontier town has a new kind of sheriff. A rancher, a Ranger, and a Civil War veteran, John Horton Slaughter is a true-life hero. And he’s here to bring Law and Order to the Wild West. A beautiful woman, a powerful Mexican rancher, and an exotic new breed of cattle come to John Slaughter’s San Bernardino Valley ranch, along with the prospect of making a small fortune. While Slaughter’s men are out keeping the peace in Tombstone, an act of betrayal turns up the heat under his own roof, and a killer is stalking Slaughter’s wealthy Mexican guest. When Indians raiders attack Slaughter’s ranch, it is only the first shot in a bigger, blazing Arizona bloodbath. The real enemy is coming next: armed to the teeth, driven by vengeance, and deep into a killing spree that only John Slaughter alone can stop . . .
