31. Utah Blaine Louis L' Amour
Interesting plot line and set of circumstances. The book opens with the lynching of a rancher by his foreman and a group of rapacious vigilantes. Blaine happens to be hidden close to the scene by chance, and is able to cut the rancher down and save his life. Utah then goes on to wage a one man war eliminating the perpetrators. He is successful, and wins the girl in the process.
Really liked this one. Highly recommended,
