Anyone have any Orson Scott Card book recomendations?

I read Ender's Game about a decade ago, but recently got back into it when I saw Ender in Exile and Ender's Shadow in an airport bookstore.  After reading those, I'm hooked.  I just bought Shadow of the Hegemon, and can't wait to get started on it.  Can anyone give me some book recommendations of other books by him?  Are there other authors out there that I might like, knowing that I like his work?  As you might be able to tell, I'm totally clueless on who are good modern-era authors, so any help would be appreciated. 

I've never read any Card myself, but I always hear people say good things about Speaker for the Dead

Isn't Shadow Complex tied to one of Card's books?

I recommend boycotting Orson Scott Card.

I remember hearing about an Orson Scott Card boycott once, but I can't remember what it was about. Care to fill me in?
