Absolutley AMAZING!!! I decided Orson Scott Card is like the God of writing. I love this book to death. Best Sci-Fi book in the world (Other than Enders Game of course). I don't know what to say. Sppechless. Oh I do want to say that I had to read over the scientificy stuff a couple times to understand, but for someone to think it up? Mind boggling awesome. Absolutley amazing.
