Query: Not like DaVinci, not even close

This over-hyped book was a real disappointment. Stuffy. self-serving. Obviously written by Princeton undergraduates, and interesting only to them. Adequately written, but short on mystery, pacing, and style. NOT like DaVinci Code. NOT like Umberto Eco. The mystery in the book is obvious. The code section is too short. I'm glad I got this book for free - it's not worth paying for!
