Ches, Navajo Indian boy, did not go to the American government school. He hid in the caves to escape the officer. But Carrie, his cousin, an Indian girl, did go. When she returns after four years, she is crammed full of ways and notions that her people disapprove. Old and new ways meet and conflict as an old medicine man gives them a turquoise frog which sets off a series of exciting adventures. Distinctive style with real characterizations, authentic background and ancient legendry. Good background school and library material in handling of a controversial subject.
