Riders of the Purple Sage - Zane Grey
Arguably Zane Grey's most popular novel and a forerunner of the western genre, Riders of the Purple Sage tells the story of a Mormon woman caught between the persecution of religious zealots and several Gentile gunmen seeking to lend her a helping hand. Set in Utah during the nineteenth century, this novel offers an early critique on the practice of polygamy and plural marriage in the Old West.
