Border Bravados (Trailsman Series #308)

It's bad enough that while leading a wagon train through Arizona Territory to the boomtown of Genesis, Skye Fargo and party get ambushed by bandits. But when they reach Genesis, all that's left is a burned-out ghost town, thanks to a sadistic gang leader and his vicious but vivacious girl. Now, with a terrified pack of pioneers to protect, the Trailsman finds himself up against a mad murderer, and a woman sent by the devil himself.
