What's that supposed to mean?
I haven't read it, but know people who have. I probably won't read it because I hate reading. I don't even read my textbooks for class. I'm more of a "watch the movie" kind of person.
Personally, I think the thought of DiVinci putting codes in his work is kind of dumb and I have a better chance of cracking the Creed mystery (HC coordinates, locations, picture meanings, that whole crest thing, etc)
