As always with Dan Brown books, it was a great mystery, it was fast paced (lots of short chapters which is awesome, but every chapter end in a mini cliff hanger, which makes it hard to put down!), and there was great imagery of the European locations (view spoiler)[(Florence, Venice and Istanbul) (hide spoiler)]. If you're not a travel junkie, you might get bored with all the description of landmarks and historical site and museums, etc., but if you're like me you'll love it :-) The subject matter is a little harder to swallow, but I think that's kind of the point. Don't know if I'd call it my favorite Dan Brown, but it was really great!
