Langdon or rather Dan Brown's 4th adventure. Admittedly, 'cast' and plot are very familiar...the Woman, the Chase, the Mysteries. But still, Brown's style of writing once again is fast and dynamic, perhaps already hinting at the next movie?! One certainly has a vivid picture of Tom Hanks in the mind while the story unfolds. A must for Langdon Fan and a good book to become one.
