The Mysterious Rider - Zane Grey

This book has all the elements of a classic Western, including rustling and gunfights, but at its heart is the battle between good and evil, between duty and love, between selfishness and self-sacrifice. The ‘mysterious rider’ of the title arrives at White Slides ranch, and his coming will have major consequences for many of those living there, not least for Columbine who is promised to a man she cannot love.
