What about The Da Vinci Code? That's such a common book to read, but it's still a great one. BTW, if you liked that book, you should read any of his other 3 books he has out (Dan Brown), they are all pretty damn good. Deception Point is my favorite actually, and was more enjoyable than Da Vinci Code.

I recently read a book about Ted Bundy by Ann Rule. Now that book was intense, especially since the author knew Ted Bundy in real life, worked with him, socialized with him, etc. throughout the whole killing spree and she had no idea it was him. Great book.
