Delightful. Absolutely the best word to describe this book. Reminiscent of a Dan Brown novel and an Indiana Jones adventure, with a younger and more modern feel. There are lots of really great laugh aloud moments as well. "The thinnest tendrils of dawn are creeping in from the East. People from New York are softly starting to Tweet." HA! As a West coast Twitter-er, this really cracked me up. It did get a little hokey in parts, but still overall: delightful.
