No one in the small Texas town of Clark Springs knows that their minister’s real name is Rule Cordell, or that he used to be one of the most notorious outlaws the Confederacy had ever seen. He’s been trying very hard to put his days as a pistol-fighter behind him, but that’s getting harder to do lately. When his friends and neighbors are threatened with losing their family spreads to a cunning carpetbagger, Rule realizes it’s time for his preacher’s collar to be replaced by a pair of .44s. But he won’t be able to do it alone. If he’s going to rid the town of this ruthless evil, he’ll need to call on a very special group of warriors-the Sons of Thunder!
