"I've watched through his eyes, I've listened through his ears, and I tell you he's the one. Or at least as close as we're going to get."

"That's what you said about the brother."

"The brother tested out impossible. For other reasons. Nothing to do with his ability. "

"Same with the sister. And there are doubts about him. He's too malleable. Too willing to submerge himself in someone else's will."

"Not if the other person is his enemy."

"So what do we do? Surround himself with enemies all the time?"

"If we have to."

"I thought you said you liked this kid."

"If the buggers get him, they'll make me look like the favorite uncle."

“All right. We’re saving the world, after all. Take him.”

Andrew "Ender" Wiggin is just six years old when he is brought to the orbital Battle School, to be trained to command humanity's space fleet in a desperate fight against alien invaders. Not that he was allowed much of a childhood before that, either. The military had been grooming him every since he was born. In fact, after realizing the potential in his older brother and sister, and that those two were too unstable to control, the military had even commissioned his birth, making him a Third, a social stigma that set him even more apart from other children than the monitor on his neck or his superior intellect already did.

An amazing book. Gripping plot and characters aside, you have to be impressed by Card's accurate vision of the future. People have always-connected tablet devices, and engage in discussions on online message boards, using pseudonyms for which they have to first build a reputation, and from time to time law enforcement tries to find out real identities. War games are fought in simulators, and it is impossible to tell the difference between a video game and a real battle. All in a novel that was published in 1985, based on a short story from 1977.
