Here's a suggestion. If you haven't already, try Cryptonomicon by Neal Stephenson. Stephenson is a guy who really understands what he's writing about. Not taking anything away from Dan Brown, but I'd say Cryptonomicon is taking it up another level. I feel safe in saying that Charles H. would agree with me.

>I read both of those as well. I've read all of Dan Brown's books. Great author.

>>Looks like a good book from what I read on Wikipedia. I'll read it. Two books I like are "Digital Fortress" and "Deception Point" both by Dan Brown.
