Man its hard to believe people did not read the Harry Potter books at least. Those books were like crack back in the day. The only thing I got more hyped for than new PS2 games as a young teen.
Angels and Demons is one of my favorite books. We only had to read ~80 pages for some weird school project. But I could not put it down.
