I'd like to offer a little advice on the order in which you read the books. After Ender's Game you should read Ender's Shadow, then Shadow of the Hegemon, followed by Shadow Puppets. Save Speaker for the Dead, Xenocide and Children of the Mind for last. Those three are the original sequels to Ender's Game but take place many years in the future and are more like adult fiction than Ender's Game. They're all really good books though.
Oh, and I'm not back, I haven't made a triumphant return, I just saw this thread and needed to post this because I love the Ender books... K, bye...
JAWA!!!... ok, for good this time... bye...
