It was the riskiest job Shane Preston and Jonah Jones had ever taken on. The Texas Rangers wanted them to ride into a lawless town called Sombrero and kidnap Lobo Dawson, a prominent member of Sam Hashknife's notorious outlaw gang. If they could fetch him back to Ranger headquarters, it was hoped that he'd reveal the location of Hashknife's hideout in return for his own freedom. But Lobo Dawson proved to be a tough prisoner to hold, especially when they joined a band of mismatched passengers aboard the last train to Gun Ridge, and the final leg of their journey back to safety. As the old loco hauled them across the pitiless Llano Estacado, Shane and Jonah found themselves faced with all kinds of treachery. and to save a young newlywed from life as an outlaw's woman, and to get even with the sadist who'd dared to whip Shane's horse Snowfire, the two gunmen crossed the blazing desert on foot to take part in an explosive showdown.
