I've read all his books except the new one The Solomon Key which has not yet been published. i rate his books in the order of highest to lowest
1. Da vinci code
2. Angels & Demons-pervious favorite
3. Digital fotress-inspired by Sidney sheldon's Doomsday Conspiracy
4. Deception Point- an ok book.
I love his writing style

I think u have to be abit of a sci fi buff to appreciate digital fortress, i just loved it
but i do agree angels and demons was really good.
Davinci Code was absolutely brilliant, the mix of fact and fiction,,,,, awesome! couldnt put it down
my aunt who is a serious pentecostal started casting out demons from me, when she discovered what i was reading

LOL!!!
