What Is The Theme Of Ender's Game

Andrew Wiggin, or Ender, was selected to attend the Battle School. The Battle School is where soldiers and commanders are trained to destroy the Buggers, an alien species that had twice almost wiped out the entire human race. He does have a choice of not going, but he chooses to, merely to escape from his violent brother Peter and to ensure that his beloved sister, Valentine, will never be harmed by the Buggers.
Battle school turns out to be nothing like he expects. Endless schoolwork and competing with peers sharing similar levels of intellect is one thing, but above all, students are grouped into armies to play the battleroom games- mock battles played in zero gravity that eventually turned best friends into rivals and enemies.
As the days go by, lies start to uncover. The games are not just games, and soon he realized- his real enemy is not the Buggers.
Not tears of pity, but of real emotions that last forever in your heart.”--- MAC News “Ender’s Game is a novel that indeed deserves all its praises, and is amongst the greatest works of literature ever written” --- Toronto
