Ender's Game (Ender Saga #1)

"Earth has been under attack for generations. An alien race is poised for a final assault. At the Battle School, Andrew "Ender" Wiggin thinks he is playing computer war games; he is, in fact, engaged in something far more desperate. Is Ender the general Earth needs? The only way to find out is to throw the child into ever-harsher training, to chip away and find the diamond inside--or destroy him utterly. Ender Wiggin is six years old when it begins. He will grow up fast. But Ender is not the only result of the experiment. The war with the Formics has been raging for a hundred years, and the quest for the perfect general has been underway for almost as long. There are other remarkable children at the Battle School--Ender's allies and enemies. And Ender's two older siblings, Peter and Valentine, are every bit as unusual as he is, but in very different ways. Between them lie the abilities to remake a a world. If, that is, the world survives"--Back cover.
