I've read all of OSC's books, follow his cult at hatrack.com, and went to Enderscon. I just finished re-reading his Worthing Saga this weekend, and I must say, in the spirit of the 4th of July, nobody writes about the unquenching quest for freedom and liberty being as vital as breath than Orson Scott Card.
Best sci-fi author since Asimov, most beautiful short-fiction writer since Le Guin.
