Buffalo medicine

Spanish Bit Saga, book 4. Owl's father had changed the lives of the People by bringing the horse from his native Spain, but now the younger son of that legendary chief must make his own contribution by learning the way of the buffalo from an ancient medicine man. He will then pursue his own vision quest, embarking upon a perilous journey through savage lands in which he will be captured by the Peoples's enemies; enslaved in Spanish mines where he wins the heart of a brave and beautiful woman. Awaiting Owl is honor among the People and a deadly rival who claims that honor for his own.
