This is the final volume in science fiction writer Octavia Butler's Xenogenesis trilogy, which chronicles the efforts of the alien Oankali to interbreed with the human survivors of an Earth-wide nuclear war. Jodahs is the first human/Oankali construct child to become an ooloi, the Oankali third gender responsible for directing the genetic and biological alterations in the species and for creating the children in a mating group. Unfortunately, Jodahs can't quite control its newly developed abilities, and may have to be exiled from the Earth to prevent it from inadvertently harming itself and others.
