From the back of the book: In 1972, a crack commando retired from the military to a normal life with the wife of his dreams and a hope for a better future. Growing restless and realizing that his true calling was a life as a soldier of fortune, he found himself a few good men working in the American underground and they formed a crew. Today, they survive as soldiers of fortune. If you have a problem, if no one else can help, and if you can find him....maybe you can hire Mark Hazzard, Merc.
