Frog,

Read the others - they are fantastic. Angels and Demons makes for a cracking read. Deception Point and Digital Fortress are both very good, but not quite up there with the other two.

Dan Brown is up there with Wilbur Smith as being a superb adventure writer, and both have the ability to write "un-put-downable" novels.

As much as I enjoyed the Da Vinci Code, there is a lot of rubbish spoke about a lot of the stuff. However, if it gets people interested in more cultural things, it's no bad thing.
