Morengaru, a strong young hunter, has been cast out by both his mother's people, the Kikuyu, and his father's people, the Masai. Every day he misses human companionship, and soon he feels as though he's becoming more like the animals around him. When Morengaru has the chance to belong again, he seizes the opportunity. Then he faces the greatest challenge of his life: living among the baboons, still clinging to his humanity, hoping someday to return to his people.
