Guns of the Waste Land recasts the legends of King Arthur as an American Western. Set in the late 19th century outside the West Texas town of Bretton, this third volume continues the stories of the men and women devoted in their own ways to Sheriff Ardiss Drake: Percy Murratt, still living with Ardiss, is in love. Unfortunately, so is Ardiss' foster brother, Caleb and with the same woman. Gary Wayne Orkney has recovered as much as possible from the beating he received from Lancaster O'Loch and desperately wants to ride a horse again and continue is service as a deputy. Reverend Merrle Tallison is considering leaving Bretton and finding a life for himself. Finally, Ardiss' estranged wife, Guernica, continues to seek closure for the events that brought her to the wilds of the Waste Land.
