While on a class trip, twelve-year-olds May and Evan are transported from contemporary Phoenix into a desert land peopled by six tribes, each of which has its own, innate magical skill. Soon May and Evan discover that these magical powers are fading, and they become caught up in the tribes’ struggles between themselves, as well as with another mysterious new Enemy. This fantasy weaves together the natural history and folklore of the American Southwest into a story for ages 8-12.
