I've read Ender's Game by Orson Scott Card a couple of times over the years. But I decided to listen to the audio book this morning...it's as moving as the book. The first time I read it, I didn't see reality coming. But even after that first time when I knew it wasn't a game, it was still powerful. It isn't one of those books that depends on the plot for its grip. The character development is superb.
