In the first book of the series, ''
Ender's Game'', Ender is the youngest and most well-rounded of three children; his parents received permission to have a third child, which is rare because of the state's strict
two-child policy. His existence was called for by a program aiming at producing commanders for humanity's war against the
Formics, or "Buggers". Ender is bullied at school for being a "Third", particularly by a bully named Stilson. After Stilson engages him in a fight, Ender beats him up so severely that the boy is hospitalized and subsequently dies, although Ender does not learn of this until much later. Ender is tormented by his brother
Peter, a
sadist, who resents the attention Ender gets from the military. His sister,
Valentine, is his protector and only friend. When he is accepted into Battle School, he is brokenhearted at leaving her, but she assures him that they will always have a bond. Battle School is an
Earth-orbiting space station that trains and evaluates military
child prodigies, with the goal of finding the leader they need to win the war. Ender is exposed to significant emotional anguish and physical danger, but it soon becomes clear that he is an exceptional individual, even among the elite students. Ender excels in academics, his main interest being a team-based three-dimensional
laser tag competition in the
zero-g Battle Room. He becomes a masterly player and strategist, and is eventually assigned command of Dragon Army. He molds this group of unwanted students into the most successful army in the history of the school. Ender's unprecedented success engenders his fellow commanders' jealousy, who subject him to torment. The lead bully, Bonzo, attempts to kill Ender in the shower, but fails. Ender kills Bonzo without knowing it. With time running short, he is transferred directly to Command School on Eros, bypassing other schools Battle School graduates would normally attend. There he trains in interstellar fleet combat with
holographic simulators. After Ender masters the game, it changes from one with direct control of ships to one where he relays commands to his classmates from Battle School:
Julian "Bean" Delphiki,
Alai,
Shen,
Petra Arkanian,
Dink Meeker,
Crazy Tom,
Hot Soup,
Fly Molo,
Vlad,
Dumper, and
Carn Carby. Under the tutelage of Mazer Rackham, the legendary savior of humanity in the previous war, Ender and his trusted companions take on a grueling series of ever more difficult battle simulations and emerge victorious every time. The final battle takes place above a planet against an enemy with an overwhelming numerical superiority. Ender perceives this as an unfair test and resolves to break the rules. Worn down almost to the point of breaking, he thinks this will convince his instructors that he is not the person to lead the Fleet into battle against the Formics. Instead of fighting a hopeless battle against the enemy, Ender orders his squadron leaders to conduct a series of seemingly purposeless skirmishes. The enemy does not realize until too late that Ender's fleet is gradually drawing closer to the planet. When Ender's surviving ships are close enough, he sends them to destroy the planet itself using Doctor Device, a weapon that destroys matter, but only if it is concentrated enough. Only a few ships manage to get close enough, but they destroy the planet. Afterwards, he is told that it was not a simulation; he and his classmates had been unknowingly issuing orders to real ships in real battles. The last battle destroyed the Bugger homeworld and eradicated the Bugger species. Ender is hailed as a hero, but he is stricken with guilt for having unknowingly committed
speciocide. His subordinates are returned to Earth to their various home countries, but Ender is too potent for any one country to have. War would break out over him. So, Peter, who is becoming a major political force on Earth, brokers a deal in which his brother is sent into permanent exile. Ender journeys with his sister Valentine to one of the colonies being established on the now-abandoned Bugger worlds. Once there, he discovers a fertilized
pupa of a Queen Bugger, hidden in a place that the Buggers designed for him to discover by modeling it to resemble part of an interactive computer game he played during his years in Battle School, which they found out during his dreams of them in Command School. The pupal Queen is capable of restoring the Bugger species. Through rudimentary
telepathic communication with the Queen, he learns that the entire conflict had been a mistake arising from the inability of the two species to establish communication with each other. He also learns from the Queen that the Buggers regretted having mistakenly fought humans and forgive Ender for destroying their world. Ender promises to find the Queen a home to reestablish her people in safety. Ender writes a book anonymously called
The Hive Queen, which tells the story of the war from the Formic perspective and starts to change public opinion of him. Peter, who has become the Hegemon, the head of the world government on Earth, recognizes Ender as the author and asks him to write a second work, about him. Ender authors
The Hegemon. The two books become very influential, and eventually they are always published together. Ender and Valentine begin to search for a planet where the Queen can restore her race. ==
