Guilty: Prequel to the Hell's Butcher Series

Gunfighter Frank Butcher is dead, shot in the chest by a U.S. Marshal who got the drop on him in a Tombstone saloon. Now he finds himself in the underworld, a twisted, terrifying version of the real world, where he must face judgment for all the people he's killed. The judges of the underworld--Morgan Earp, Wild Bill Hickok, and a former marshal who bears Frank a deep grudge--decide Frank will be tested to determine his damnation or salvation. Given a native guide to help him, Frank must face five of his kills, only one of which was justified. The rules are simple: shoot only the justified kill, sparing the others. And don't die, for death will leave him trapped in the underworld, reliving his sins over and over for all eternity.
