"What sort of men rob a train, and after they have their loot and can make a clean getaway, start shooting everyone on board? Billy Young doesn't know the answer to that question. But one of the passengers they kill is his brother, and Billy intends to do whatever it takes to find out. Once he does, he'll exact his vengeance. He'll do it with pleasure. And he'll exact it in blood. Wyoming is now a state and the legislature down in Cheyenne is making plenty of brand-new laws. But not much has changed out on the range. The big outfits still make the rules, and if the little operators and the lawyers and the politicians don't like it--well, there are ways of dealing with them. They try to teach that lesson to Billy Young, but Billy is stubborn. And a slow learner. There's only one rule Billy cares about: Blood for Blood." --,(Source of summary not specified)
