Not bad for a first in a series. The only criticisms I have is that the dialogues wavered between the Americans sound slightly English and the Brits sounding slightly American. Also, felt the action at the end was a bit Hollywood, almost as if the editor called for more theatrics to add thrills, but wasn't necessary (IMHO) and was a little contrived and predictable. But all in all an ok book and would appeal to the Da Vinci Code lovers.
