SHOOTOUT AT SKULL ROCKS by Polly McBee Hutchison

After the Civil War, Linc Wolf fled to Texas where at the age of fifteen in
revenge for the death of his mentor he killed his first man. His deadly
skill with a gun soon earned him a reputation, that forced him to keep
moving trying to avoid ambitious men who sought to make their own
name at his expense. As he grew older, he longed for a life free from
killing. When a small fortune came his way he saw a chance to leave
his violent past behind. Setting his sights on Wyoming, he hoped to
find the respectability he craved. The past is not so easily escaped. He
was forced to use his gun again, knowing it would cost him everything
he had built, including the woman he had grown to love.
