Galveston Gunman by Bill Crider
The story concerns a young man in 1880 who has a large sum of money stolen from him. The problem is that he'd like to have it back and the guys who took it from him are opposed to this proposition. The book moved at a quick pace, had just enough turns and twists, and action was even coupled with romance in the second half. I've never read a western before, but I'm heartily glad I've read this one.
