I really like Dan Brown's books, what other books do you recommend?

I've never really liked ready, probably because if the book does not get my attention right away I won't finish reading it. But I decided to read "The Da Vinci Code" and was absolutely amazed, then I read "Angels and Demons" and was blown away further, best book I have ever read. "Deception Point" was good as well. So what other books do you recommend?
