Just finished reading it. The first half was so slow/boring that I dozed off 3 nights in a row while reading it. And a Dan Brown novel is something that one wants to finish in one long session only. That's how I went thru the earlier novels of his. The second half was well paced, and interesting enough to keep me occupied. Interesting story, has the regular Dan Brown start that is common to all his novels,a death at the beginning, and Robert Langdon being helped by a female that is somehow related to the person who dies/ is killed. The story was thin, and short, stretched a bit too much at the start, and then compressed a lot towards the end. Do read it if you are a Dan Brown fan. Do read it if you have an interest for European History, And Do read it if you want a decent story, with a fair bit of twists in it. All in All, I would give it a 3.5 out of 5.
