People who like this sort of thing will find it the sort of thing they like.I'm reading the new Dan Brown book, The Inferno. I'm about half way through it so far. It's set it Florence, Italy, which is kind of cool for me because I went there a few years ago, and I recognize a lot of the scenes.
If you've liked the other Robert Langdon books, you'll probably like this one.
I enjoyed it.
