I've listened to four of his as audiobooks and Da Vinci was the weakest to me. Although I did enjoy it. The movie was just fair. I'd give the book three out of five stars and the movie only two stars.
For a book that is similar but done better I like Angels and Demons. A lot of the same scenes, almost like he copied them for Da Vinci later, but overall a much stronger storyline.
My least favorite has been Deception Point. Seemed like 80% of the story was
Spoiler
My favorite has been Digital Fortress. Excellent story related to code breaking using computers. Kept me on the edge of my seat.
Are there other books he's written (I'm not sure) and that anyone would recommend?
