McFarland & Company, 2014. Soft Cover, 6 x 9 inch format, 228 pp. A literary discussion of about one-half of Zane Grey's Westerns, selected to best show the broad scope of this popular author's interest in the West. Central is Grey's ecological concern for the natural world -- its vastness, color and beauty. Close parallels are drawn throughout the book between Grey's work and the philosophy and writings of Thoreau. Note particularly Chapter 15 -- "The Vanishing American: A Thoreauvian Native."
