USA Today best-selling author Ralph Cotton exhibits the same dead-eye aim for storytelling that his fictional gunfighters show for slingin' lead. In Guns on the Border, Arizona Ranger Sam Burrack heads out into the Mexican badlands to track down the dirtiest scoundrels to ever strap on a six-gun and laugh in the face of the law. But Burrack is anything but amused, and retribution is soon to be paid.
