Haunted Mesa - Louis L'Amour

The Navajo called them the Anasazi, the "ancient enemy," and their abandoned cities
haunt the canyons and plateaus of the Southwest. For centuries the sudden disappearance
of these people baffled historians. Summoned to a dark desert plateau by a desperate
letter from an old friend, renowned investigator Mike Raglan is drawn into a world
of mystery, violence, and explosive revelations. Crossing a border beyond the laws
of man and nature, he will learn of the astonishing world of the Anasazi and discover
the most extraordinary frontier ever encountered.
