I generally liked this novel and was leaning toward a fourth star, but I think it fell short of the great stories that preceded this Robert Langdon novel. As usual, Dan Brown weaves an interesting tale of intrigue, but he added a bit too much fluff and back story for my liking. His detailed descriptions of religious sites and places in Spain gave me the impression I was reading from a Wikipedia post or even a travelogue.
The plot was good and the author keeps you guessing for more than half the novel. It didn’t move as quick as other Langdon stories, but as usual the story and characters were realistic, making for a good read.
