Desert Crossing — Luke Short

Dave Harmon had a job to do: take a girl and the guns the army desperately needed across the burning malpais to Fort Whipple. But the desert was Apache territory. Faced with scorching sand and killing thirst, savage Apaches and ruthless outlaws, Dave found treachery within his own wagon train. Single-handed, he had to destroy everyone who stood against him or lose the guns, the girl, his life.
