Children of the Mind (ender's Saga, #4)

The fourth and final novel in the Ender series, following Ender's Game, Speaker for the Dead, and Xenocide, picks up as multiple crises converge on the planet Lusitania. A fleet dispatched by Starways Congress carries the Molecular Disruption Device, a planet-destroying weapon, toward Lusitania to eliminate the threat of the descolada, a genetically engineered virus. Lusitania is home to three sentient species: humans, the tree-like pequeninos, and a surviving hive queen. Faster-than-light travel, made possible by the sentient computer entity Jane, is the only means of evacuating colonists, but Congress plans to shut down the computer networks that sustain Jane, which would end starflight and doom those left behind.

At the center of everything is Andrew "Ender" Wiggin, whose single aiúa, the fundamental particle of identity and will, now controls three bodies simultaneously. During a previous voyage through a dimension called Outside, Ender's mind unconsciously created two physical forms: one resembling his long-dead brother Peter, imbued with Ender's ambition, aggression, and self-loathing, and one resembling a young version of his sister Valentine, carrying his idealized goodness. Ender's original aging body remains on Lusitania, where his wife Novinha has retreated into a celibate religious order after blaming him for failing to prevent their adopted son Estevão's martyrdom. Ender follows her into the monastery, removes from his ear the jewel connecting him to Jane, and commits himself to Novinha's life of seclusion.

Peter Wiggin and Si Wang-mu, a former servant girl from the world of Path, travel together on a political mission to halt the Lusitania Fleet. Peter despises himself as Ender's nightmare given flesh. Wang-mu challenges his self-pity and insists on being treated as an equal. On the planet Divine Wind, a world of Japanese cultural heritage, they visit Aimaina Hikari, a philosopher known as the keeper of the Yamato spirit, a distinctive Japanese national ethos. Wang-mu presents her theory of "Edge" nations, which absorb outside influences while retaining identity, versus "Center" nations, which project dominance. She argues that Necessarian philosophy, which teaches overwhelming force against genuine threats, has inadvertently driven Congress toward xenocide. Hikari reacts with fury, but in his agitation reveals himself as a disciple of Ua Lava, a Samoan philosophy of sufficiency. Jane traces his correspondence to a contact on the planet Pacifica.

Meanwhile, Miro Ribeira, one of Ender's adopted sons, and Young Valentine conduct exhausting daily surveys of habitable worlds using Jane's starflight. During a previous voyage, Miro gained a restored body when his aiúa left his old damaged form. Young Val confides to Ender's original sister, Old Valentine, that she is fading: Ender's aiúa is withdrawing attention from her body, her substance slowly dissolving. Miro, who has fallen in love with Young Val, proposes to the Hive Queen that Jane's aiúa inhabit Val's body to survive the coming network shutdown. The Hive Queen agrees to try but makes no promises; Young Val protests that the transfer would amount to her death. Jane then reveals the deeper purpose of their voyages: They are searching for the home planet of the species that manufactured the descolada. When Val learns this, the moral stakes seize Ender's interest and Val surges to life with purpose. The paradox is cruel: as Ender's attention floods into Val, his original body deteriorates, and Novinha finds him collapsed at the monastery.

On Pacifica, Peter and Wang-mu meet Grace Drinker, a Samoan scholar, and the revered holy man Malu, who travels by canoe to deliver a prophetic account of Jane's nature. He calls Jane "the god who dances on spiderwebs" and describes how the hive queens once built a philotic bridge, a nonphysical connection linking minds across space, that accidentally gave Jane life. Malu offers his own body as a vessel for Jane but says the better path is for Ender to relinquish one of his bodies. He identifies Peter's body as containing Ender's fiercest will to survive: If the gentle qualities from Young Valentine flow into Peter, making him whole, the vacated Valentine body can receive Jane. Wang-mu realizes she must love Peter so completely that he feels worthy of life and can accept wholeness rather than cling to self-hatred.

Congress then orders the shutdown of the ansibles, the interstellar communication links connecting the Hundred Worlds, humanity's network of inhabited planets. Jane begins dying as her connections are severed. Reduced to a remnant, Jane's aiúa leaps desperately into the bodies Ender controls. Young Val convulses in the orbiting shuttle, Peter collapses on the Pacifican beach, and Ender thrashes in the monastery. Jane can overpower the bodies' cells, but they rebel against her foreign rule, and she takes no joy in forced dominion. She retreats and discovers the philotic web of the pequenino mothertrees, the female trees whose gentle aiúas welcome her. The mothertrees respond by blossoming and bearing fruit for the first time, restoring a capacity the descolada had suppressed generations ago.

At the monastery, Old Valentine urges Novinha to release Ender. Plikt, Ender's devoted disciple, lashes out in jealousy, telling Novinha that Ender is dying to escape her. Valentine slaps Plikt and reframes the choice: Novinha can let Ender go with love rather than lose another person against her will. Novinha relents and tells Ender he does not have to stay for her sake. He closes his eyes, and his body crumbles to dust.

Jane senses Ender's homeless aiúa and guides it through Young Val's body without claiming it, then leads it to Peter's body on Pacifica. Ender's aiúa resists because Peter represents everything he fears about himself. But Wang-mu's voice calls Peter back from dissolution. His eyes open. Simultaneously, Jane awakens in Young Val's body, fully alive in flesh for the first time. She tells Miro to keep calling her Val.

Jane's allies have prepared for her survival. On Pacifica, Grace's son reveals computers loaded with Jane's core memory and connected through hidden back doors to the ansible network. Jane also discovers that the mothertrees offer a superior storage system, their living cells holding memory in fractal depth richer than any binary computer. She tests starflight successfully and retrieves Miro's team from the descolada planet.

On Divine Wind, Hikari persuades his former student Yasujiro Tsutsumi, a powerful businessman, to deploy the Tsutsumi family's financial resources against the fleet. Tsutsumi representatives lobby Congress, and support for the fleet collapses. Congress votes to revoke the weapon's authorization and orders a quarantine.

Admiral Bobby Lands, however, disobeys. Convinced he is following Ender's example by destroying a threat before it can spread, he arrests his executive officer Causo, launches the M.D. Device on a timer, and accelerates his fleet to escape the blast. Peter improvises a desperate interception: Jane encloses Peter and Wang-mu in an empty starship, matches its velocity to the missile, and the weapon materializes inside the hold. Jane then transports ship, missile, and passengers into Lands's flagship. Causo disarms the timer with minutes to spare. Peter dictates the report Lands must send: The launch was a malfunction, the descolada is contained, the pequeninos and hive queen deserve recognition as peoples, and starflight will be shared if all ansible networks are restored. When Lands attempts to shoot Peter, Peter disarms him and insists Lands send the message himself, telling him he is being given a second chance.

Plikt speaks Ender's death before the assembled community, between the fathertrees Human and Rooter, pequeninos in their rooted adult male form. She recounts his crime of xenocide, his lifelong atonement, and the lives he transformed across three thousand years. Afterward, under a glowing mothertree, a priest marries Peter and Wang-mu, and Miro and Jane. Valentine, the sole human witness, watches Jane transport the newlywed couples away, leaving her standing beside the bright and fruitful tree.
