i agree with a lot of people here, Dan Brown's book are great and they keep you connected and intriged, even thou this is his worse book, it still keeps you involved. Awful story, they chanfed a lot of the original book, Peter is Katherin's brother, not his father, which by the way was performed awfully by a trans person, Sato is much meanier in the book and the series is more Langdon's friend but acting was awful too. It is a very confusing series of event in the book, but they made it so much worse in the tv series.
