Is the da vinci code appropriate...?

Yes, the Da Vinci Code is a great book for a teenager or adult to read. It is a fiction book but has true facts put in there from history (like Wiccan having strong females that scared Catholics of old and such) but you are old enough to do the reseach and make up your own mind. Books are there for you to read and yes, at times, even open your mind to new ideas.
