Ender's Game by Orson Scott Card

This is a first. I desided to broaden my horizions this week with a science fiction book by Orson Scott Card titled Ender's Game. It is about a futuristic boy, Ender Wiggins, being chosen to go into military school. The commanders at the school think that he is the one to save the world from the evil Buggers.
It was an easy read. It did seem a little immature for my standards. I would recommend it to a guy that doesn't have a lot of time to read, or a 12 year old.
What are your ideas?
