A hostile alien race attacked Earth, and if not for the legendary heroics of Fleet Commander Mazer Rackham, all would have been lost. In preparation for the next attack, Colonel Hyrum Graff is training only the best young children. Ender Wiggin, a shy, but brilliant boy, is soon ordained by Graff as the military's next great hope. Once at Command School, he's trained by Mazer Rackham, himself, to lead them into an epic battle that will determine the future of Earth and save the human race.
