Ender's Game

This week I'm going for SF. I choose Orson Scott Card's Ender's Game. This is the first book in Card's superb Ender sequence, although it easily holds its own as a stand-alone. Humanity is attacked by aliens and almost wiped out. Child genius Ender Wiggin is top of the heap in the government's military genius breeding program. A race against time springs some surprises for both Ender and the invading forces.
