'Squire' Allen rescues a pale, blond-haired Red-Indian boy, and recruits him for the grail quest. At a mysterious structure on the Ohio, Squire is struck from behind. When he comes to he is looking at a tall red-haired ëNatural' girl. Her companion is shape-shifting Coyote-Witch. Leahna joins the men on a trek to find her ancestors, the Mandan.
