Free Anderson thought the war was over. But his battle to survive is only just beginning. An old nemesis has been shadowing his every step, just waiting to take revenge. And sure enough, before long Free finds himself framed for rustling and about to be hanged. There's only one man who can save him--a former army buddy turned mustanger named Parks Scott. Problem is, no one knows exactly where Scott has gone. The effort to find the free-roaming former lieutenant launches a wild chase across Texas that draws in some of the most famous names in history, including Wild Bill Hickok, Charles Goodnight and George Armstrong Custer.
