In 1992 author Douglas Preston and his wife and daughter rode horseback across 400 miles of desert in Utah, Arizona, and New Mexico. They were retracing the route of a Navajo deity, the Slayer of Alien Gods, on his quest to restore beauty and balance to the Earth. More than a travelogue, Preston's account of their "one tough journey, luminously remembered" (Kirkus Reviews) is a tale of two cultures meeting in a sacred land and is "like traveling across unknown territory with Lewis and Clark to the Pacific" (Dee Brown, author of Bury My Heart At Wounded Knee).
