All of humanity must share the world with uncanny, unimaginable alien creatures after war destroys Earth, in an omnibus edition containing three class science fiction novels--Dawn, Adulthood Rites, and Imago. The acclaimed trilogy that comprises Lilith's Brood is multiple Hugo and Nebula award-winner Octavia E. Butler at her best. Presented for the first time in one volume, with an introduction by Joan Slonczewski, Ph.D., Lilith's Brood is a profoundly evocative, sensual--and disturbing--epic of human transformation. Lilith Lyapo is in the Andes, mourning the death of her family, when war destroys Earth. Centuries later, she is resurrected, by miraculously powerful unearthly beings, the Oankali. Driven by an irresistible need to heal others, the Oankali are rescuing our dying planet by merging genetically with mankind. But Lilith and all humanity must now share the world with uncanny, unimaginably alien creatures: Their own children. This is their story.

Lilith Iyapo has given birth to what looks like a normal human boy named Akin. But Akin actually has five parents: a male and female human, a male and female Oankali, and a sexless Ooloi. The Oankali and Ooloi are part of an alien race that rescued humanity from a devastating nuclear war, but the price they exact is a high one the aliens are compelled to genetically merge their species with other races, drastically altering both in the process. There are "pure" humans who choose to resist the aliens and the salvation they offer. These resisters are sterilized by the Ooloi so that they cannot reproduce the genetic defect that drives humanity to destroy itself, but otherwise they are left alone unless they become violent. When the resisters kidnap young Akin, the Oankali choose to leave the child with his captors, for he the most "human" of the Oankali children will decide whether the resisters should be given back their fertility and freedom, even though they will only destroy themselves again. -- adapted from Goodreads info

"Since a nuclear war decimated the human population, the remaining humans began to rebuild their future by interbreeding with an alien race -- the Oankali -- who saved them from near-certain extinction. The Oankalis' greatest skill lies in the species' ability to constantly adapt and evolve, a process that is guided by their third sex, the ooloi, who are able to read and mutate genetic code. Now, for the first time in the humans' relationship with the Oankali, a human mother has given birth to an ooloi child: Jodahs. Throughout his childhood, Jodahs seemed to be a male human-alien hybrid. But when he reaches adolescence, Jodahs develops the ooloi abilities to shapeshift, manipulate DNA, cure and create disease, and more. Frightened and isolated, Jodahs must either come to terms with this new identity, learn to control new powers, and unite what's left of humankind -- or become the biggest threat to their survival."--Provided by publisher.

The human race, now infertile, fights to maintain its identity when the alien species, Oankali, offers to trade genetic material and bioengineering at the price of metamorphosing a new kind of being.
