Zane Grey 
Wanderer of the Wasteland [EPUB ebook] 

From the master of the western comes a novel full of romance and adventure. The story begins: Adam Larey gazed with hard and wondering eyes down the silent current of the red river upon which he meant to drift away into the desert. The Rio Colorado was no river to trust. It chafed at its banks as if to engulf them; muddy and thick it swirled and glided along in flood, sweeping in curves back and forth from Arizona to California shore. Majestic and gleaming under the hot sky, it swung southward between wide green borders of willow and cottonwood toward a stark and naked upflung wilderness of mountain peaks, the red ramparts of the unknown and trackless desert.
