El juego de Ender

Earth is threatened by an extraterrestrial race, the Buggers, who communicate telepathically and consider they have nothing in common with humans, whom they intend to destroy. To defeat them a new kind of military genius is required, and for this reason Ender has been allowed to be born, which constitutes, in a way, an anomaly, since he is the third child of a couple in a world that has strictly limited two the number of descendants. The Ender boy must learn everything related to war in video games and in the dangerous rehearsals of space battles that he carries out with his companions.
