Ender's Game (Ender Quintet Book 1)

Orson Scott Card's Ender's Game, adapted to film starring Asa Butterfield and Harrison Ford, follows a young boy recruited into an interstellar war. To develop a defense against a hostile alien race, government agencies breed child geniuses and train them as soldiers. Andrew "Ender" Wiggin lives with kind but distant parents, his sadistic brother Peter, and the person he loves most, his sister Valentine. Ender is sent to the orbiting Battle School for rigorous military training and excels in the zero‑gravity Battle Room. Growing up among artificial soldiers, Ender endures isolation, rivalry from peers, pressure from adult teachers, and an unsettling fear of the alien invaders. His psychological battles include loneliness, dread of becoming like Peter, and fierce devotion to Valentine. Meanwhile the war with the Buggers has lasted a century and the quest for the perfect general has produced other extraordinary siblings; between them lie the abilities to remake a world if Earth survives.
