An alien race is threatening to wipe out humanity in a massive League war. And Ender Wiggin is the child chosen to prevent this extinction of his own kind.

Selected by the International Fleet Selective Service, at the age of six he leaves behind his family on earth to make the shuttle flight to the Belt. There he enters Battle School, where his life is strictly disciplined to consist of mind games, computer war-games and mock battles fought with deadly earnest in conditions of zero gravity.

His genius at computer programming, his killer instinct and his compassion combine to make Ender unique. And he is pushed to the limits of human endurance to fulfill a unique destiny in the fast-approaching invasion which will decide the future of mankind.
