The Da Vinci Code by Dan Brown is a fast-paced thriller where the main characters have to decipher clues in artwork, architecture, and riddles to get to the bottom of a murder and save themselves. As a thriller, it is an O.K. pick, but not as good as Brown's Angels and Demons. The main characters discuss unsubstantiated religious ideas as if they are facts (and Brown's "Fact" page implies that they are). This may offend or annoy some readers.
