Delta lives deep in the African rainforest, secluded from her people, the H'vuribups, because she looks more human than them. Regardless of being part human, she develops abilities once lost to her kind and is seen valuable, but still an outcast. By happenstance, Delta meets a human named Julius, a geologist studying the strange land inhabited by the H'vuribups. With Julius and her H'vuribup friends Chi and Glekro, Delta discovers a dark history surrounding the H'vuribups and a plot to repeat that very history. She may not belong with humans or H'vuribups, but she will have to find her own place while saving both races.
