Modern man knows there is only one world on planet Earth, that monsters come from symbolic tales, and black magic and ravelling portals are fantasy. The White Man believes ravens, coyotes and bears are plain animals. The Hopi believe otherwise. Their history tells them this is Tu'waqachi, the Fourth World Below, the coyote is a troublemaker, and the bear is a healer and the Keeper of Dreams. Skin walkers live among them. The Navajo believe this is the Fifth World, where coyotes are tricksters, bears host evil spirits, and thunder birds bring flooding storms. The Old World collides with the New World where stone arches and natural bridges stretch across the air, and monsters roam America's National Park sites.

He confronts life and death when he gets ensnared in the Old World plot that transforms his healing totem into a ferocious demon bear that feasts on fear. Colt must navigate the Ways -- a short cut through Below -- and survive long enough to rescue Spirit Bear. Will discovering the truth about his history and skin walkers save Colt?
