Query: Orson Scott Card does it yet again.

To put it very simply, anyone who enjoyed Ender's Game will enjoy this book. As usually Orson Scott Card writes with a level of emotional clarity unmatched in science fiction today. And for those who have not entered Ender's world before get ready to experience a journey from the mean streets to the depths of space with a boy who learns what it means to be a leader. The characters are so real I found myself cheering them and crying with them. I throughly enjoyed this book and recommend it to anyone and everyone.
