This is sort of a Romeo and Juliet story set in the old west between two ranchers. One rancher gets his cattle by rustling and shady deals, the other rancher has sworn vengence against him for the deaths of family members and his cowhands. The son of the second rancher comes home but meets the daughter of the outlaw rancher before he knows what has happened. Settling the feud and saving the girl keeps the book moving at a lively pace. The story was based on an actual feud in Arizona that Zane Grey researched.
