Lilith Iyapo wakes aboard an alien spacecraft centuries after nuclear war has destroyed Earth, held captive by the Oankali—a species that survives by trading genes with other life forms—who intend to return humanity to Earth with genetic modifications and the requirement of interspecies reproduction. Lilith must choose between survival and complicity in a process she finds deeply violating. A profoundly unsettling examination of bodily autonomy, consent, and the nature of humanity.
