Grim Riders

Five years of hell.
Day after day, Nathan Partridge endured the dehumanizing, brutal conditions of the Arizona Territorial Prison until he became more animal than man. He kept his sights on his parole, his loving wife, and $80,000 in robbery money he had hidden. Then his house burned down and his wife disappeared in the flames. He busted out to get his money, only it's gone. And only his wife knew where it was hidden.
Now he's after her. And on his trail are desperate manhunters, the worst criminal scum of the Territories as well as one dogged, relentless federal marshal and two deranged bounty hunters whose chosen prey is human. But Partidge's most desperate enemy might be his own father. A man who's been in the grave for ten years.
