Orson Scott Card's classic SF novel came highly recommended to me (by my cousin and my brother) and the book did not disappoint. While I felt the outcome to the war with the aliens was predictable, the final twist (sorry, not going to spoil it for you) was unexpected and easily opened the door for further Ender adventures, which of course, there are several already. What I really liked was the "Clockwork Orange"-like approach to training the young Ender to become the greatest military genius / strategist the world has ever known. Young Ender Wiggin goes through a labyrinth of "games", some viscious, some intellectual, in creating a warrior capable to defend the Earth from the "evil" alien invaders. And along the way, the boy soldier realizes how little he wants to be the world's saviour and also how little choice he has in the matter. Very interesting, even for an adult even though the book was clearly written for a YA audience. Great SF nonetheless.
