Andrew "Ender" Wiggin is a 6-year-old army general (将军), and a gaming genius. Sometime in the Earth's future, humans have a war with a bug-like alien species, the "buggers". They use computers to control wars. To prepare for the war, all talented children study in a special school to become generals. Wiggin is one of them.

    Students play games to practise their commanding (指挥的) skills. Wiggin is the best of them. At last, Wiggin comes to his final test. The fleet (舰队) he commands in the game is the real human army. Wiggin is actually "playing the final battle" between humans and buggers. Will he win? What will happen to humans after the battle? Let's find out in the book Ender's Game, by American writer Orson Scott Card.
