Young Ender Wiggin is recruited by the International Military to lead the fight against the Formics, a genocidal alien race which nearly annihilated the human race in a previous invasion.
The war with the Buggers has been raging for a hundred years, and the quest for the perfect general has been underway for almost as long. Enter Andrew "Ender" Wiggin, the result of decades of genetic experimentation.
Is Ender the general Earth so desperately needs? The only way to find out is to throw him into ever-harsher training at Battle School, to chip away and find the diamond inside, or destroy him utterly. Ender Wiggin is six years old when his training begins. He will grow up fast.
But Ender is not the only result of the experiment. His two older siblings, Peter and Valentine, are every bit as unusual as he is, but in very different ways. Among the three of them lie the abilities to remake a world. If, that is, the world survives.
