Similar to the Da Vinci Code, but different enough that it didn't bother me. I thought the book was good. One silly thing that bothered me was that the author repeatedly used a few words that could have been replaced by other words to make it less redundant. I wanted to yell out 'Use a thesaurus!'

Overall, I'd recommend this book if you like this genre (crime, religious controversy, with a little bit of a love story thrown in for good measure).
