Andrew “Ender” Wiggin was a third — a child who should not even exist in a society with a strict two children per family limit. Why did he exist, then? Because his parents had promised to hand him over to the government if he tested well and showed promise as a potential commander in the fight against the Buggers [an alien race with whom the people of Earth were at war]. Even though military leaders were excited by Ender’s progress at Battle School and thought he might possess the skill-set needed to save humanity, Ender was kept in the dark. All he knew for sure was that Battle School offered him refuge from his sadistic older brother, Peter, while taking him away from the affections of the only person he has ever truly loved, his sister Valentine. But ruining one kid’s life to potentially save the human race is worth it, right?
