Ender's Game

by Orson Scott Card

An alien threat is on the horizon, ready to strike. And if humanity is to be defended, the government must create the greatest military commander in history. The brilliant young Ender Wiggin is their last hope. But first he must survive the rigours of a brutal military training program – to prove that he can be the leader of all leaders.

“Welcome to the human race. Nobody controls his own life, Ender.”

Orson Scott Card, Ender's Game
