holyspawn...that was fucking hilarious. I have no single favorite fictional book, some of my favorites:

Enders Game (the series is pretty good too)
Angels and Demons (once youve read one of his books, you can pretty much guess the ending of any of his others about 20 pages in though...)
The Bourne Supremecy (my favorite book of the series, the others were very good too)
Harry Potter and the Goblet of Fire
Timeline
The Lost World (the movie sucked, the book was AWESOME)
