I finished Ender's Game by Orson Scott Card, and I loved it. It was just amazing.

My only beef with it is it being considered a childrens' book. All the swearing, violence, death, philosophical themes and even a small hint of alien sex (nothing graphic, and it only lasts for a sentence but it's there) make this a book I wouldn't give to any children of mine.

But other than that, it was great. Read it.
