The second book in Octavia Butler's Xenogenesis trilogy, "Adulthood Rites," takes place years after the events of the first novel "Dawn", and it expounds more on the many social issues raised in the first book; namely issues of gender, sexuality, genetics, and humanocentrism.
In the first book, a peaceful alien race, the Oankali, has essentially saved humankind from extinction. Several hundred years after a global nuclear war has wiped out a majority of the world population and destroyed the planet, the Oankali arrive and salvage a small group of humans scattered across the globe. They "resurrect" these humans on board a vast ship floating above the Earth, which is gradually healing itself from a long nuclear winter and radioactive fallout.
The first attempts to revive humans were unsuccessful and tragic. The Oankali are, to human eyes, so monstrously alien, that most of the humans who were revived either went suicidally mad with fear or tried to attack the Oankali, which resulted in the human's deaths. The Oankali loathe killing, but they are biologically compelled to kill if attacked. As a defense mechanism, their bodies secrete deadly poison if a human touches their skin.
As a different approach, they resurrected Lilith Iyapo, a young black woman who had been mountain-climbing in the Andes after the death of her husband and son in a car accident. The aliens charged her with the task of picking and choosing humans to revive, one at a time, to gradually and carefully introduce them to the reality of their situation. The aliens rightly assume that the news would sit better when delivered by another human.
But what is the reality of their situation? Lilith gradually discovers that, in order to ensure humanity’s survival, the Oankali has done something drastic: they have made it impossible for humans to breed by themselves. The Oankali believe (and it’s not a belief so much as knowledge based on their advanced science) that humans are genetically predisposed for self-destruction. To release humans back “into the wild” would, in their opinion, be folly and futile, as humans would simply find new ways to kill each other off as a species, along with every other species of plant and animal life around it. Past history suggests that truth. Genetics confirms it.
In order to keep humankind from dying off, the Oankali have found a way to create human-Oankali hybrids, which they call constructs. Some look human. Some don’t. The breeding process involves five parents: two humans, a male and a female; two aliens, male and female; and an ooloi, a genderless alien. Humanity will live on, but it won't be recognizable.
In “Adulthood Rites”, which is set on Earth, Lilith’s child, Akin, is just beginning to understand what he is. Unfortunately, he is kidnapped by a gang of humans who have refused to accept their situation. These humans, called resisters, routinely kidnap children and sell them to different towns, to humans who want and need children, since they are now unable to reproduce themselves. Many humans find the constructs repulsive, but some take what they can get.
Akin befriends a couple, Tate and Gabe, who, in the first book, were part of a group that wanted nothing to do with the Oankali. Akin struggles to understand why these humans constantly refuse the medical help from the Oankali and why they would kill each other to, ironically, “ensure their species‘ survival”.
As Akin struggles with humans who want him dead on principle, he is also undergoing metamorphosis, which will make him more powerful and superhuman but will also, unfortunately, make him look more alien to the humans he is trying to make accept him.
Meanwhile, Lilith and Tino, Akin’s father, and the other Oankali who are his parents, are desperately trying to find him before violent resisters find him first, a meeting which could end violently for Akin and the humans.
As Akin begins to understand why these humans feel the need to survive without the Oankali’s help, he devises a brilliant plan to give those humans exactly what they want. Unfortunately, it may not be what the other Oankali want.
Like “Dawn”, “Adulthood Rites” moves at a fast, exciting pace while also offering much food for thought. Butler’s Xenogenesis series is superb science fiction at its best. I eagerly await reading the third, and final, book in the series, “Imago”.
By the way, all three books have recently been published as one book entitled “Lilith’s Brood”.
