Someone is terrorizing the Arizona border. Burning down ranches. Butchering travelers. Blazing a trail of bloodthirsty raids and robbing the railroads blind. His name is Melichus. A ruthless half-breed outlaw with a mile-long record of cruelties and crimes, he’s the most wanted man in the territory. And the massive price on his head has attracted the attention of every trigger-happy, would-be bounty hunter this side of the Rio Grande. But Luke Jensen knows something they don’t: The bigger the bounty, the deadlier the prey. Against his better judgment, Luke accepts an offer from the Great Southern Railroad to lead a posse of hired guns to stop Melichus in his tracks. Problem is, the gunmen are untrained, undisciplined, and unruly. To make matters worse, a meddlesome pair of Pinkertons are along for the ride, too. But the real trouble starts when their team gets caught in a three-sided gunfight with an Apache war party and the Mexican Army. It’s fast becoming the bloodiest manhunt Luke’s ever seen-and the final showdown could be his last . . .
