In biology, imago is the final and fully adult stage after metamorphosis. Jodahs is the final stage of the process that began with Dawn and continued with Adulthood Rites. The offspring of a mating between human and oonkali, he is something else entirely. Both the humans and the oonkali don’t know quite what to do with him. He is either the savior of the world, or the damnation.
In this brilliant and to her trilogy, Octavia Butler offers an unexpected end to her masterful account of what happens after humans do their best to destroy earth, and the oonkali, an alien race from space, do their best to save it.
