The New York Times has broken the embargo on the new Dan Brown book, The Lost Symbol, with a review of Brown's "third rip-snorting adventure". According to the newspaper, "The Lost Symbol manages to take a twisting, turning route through many such aspects of the occult even as it heads for a final secret . . . In the end it is Brown's sweet optimism, even more than Langdon's sleuthing and explicating, that may amaze his readers most."
Here is the Times review, entitled "Fasten Your Seat Belts, There’s Code to Crack".
