Why is Ender chosen?
Decades earlier, the insect-like Formics nearly destroyed humanity. Ender is a Third, a rare extra child allowed because his brother Peter was too vicious and his sister Valentine too gentle. When Ender's monitor is removed, a bully named Stilson attacks him, and Ender beats him so badly that, he never learns, the boy dies. Colonel Graff recruits him for Battle School.
↑ Back to the topWhat is Battle School like?
In orbit, children train in armies that fight mock battles in a zero-gravity room. Graff isolates Ender so that he will rely only on himself. Ender rises quickly, invents new tactics and is given his own army, Dragon, made of new recruits including Bean. He wins every battle, even when the teachers stack the rules against him.
Bonzo Madrid, humiliated by Ender, attacks him in a shower room. Ender fights back to survive. Bonzo dies, though Ender is not told.
↑ Back to the topWhat are Peter and Valentine doing?
On Earth, Peter and Valentine use the early internet to publish political essays under the names Locke and Demosthenes, gaining huge influence. Graff brings Valentine to see Ender when he wants to quit, and she persuades him to continue.
↑ Back to the topWhat happens in Command School?
Ender is sent to Command School, where Mazer Rackham, the hero of the previous war, trains him through endless simulations, with his old friends as squadron leaders. Exhausted, Ender faces his final exam: an overwhelming Formic fleet around a planet. Thinking he will be expelled if he breaks the rules, he sacrifices his own forces and fires a weapon that destroys the whole planet.
↑ Back to the topWhat was really happening?
The adults then tell him the truth. The simulations were real battles, fought by human fleets light-years away, and Ender has wiped out the Formics. They kept it secret because only a child who believed it was a game could act so ruthlessly. Ender collapses, crushed by guilt. A war breaks out on Earth, Peter rises toward power, and Ender is not allowed to return home.
↑ Back to the topHow does Ender's Game end?
Ender and Valentine travel with colonists to former Formic worlds. On one he finds a structure built from images of his own dreams, and inside it a dormant hive queen's cocoon left for him. Through her thoughts he learns the Formics never meant to destroy humanity once they understood it. Ender writes their story under the name Speaker for the Dead, then sets off with Valentine to find a world where the queen can live again.
