I have read the Twlight Book series and some people think I am a little old for them - I am a 57 year old female!  My oldest daughter calls me "a little 12 year old girl" but I disagree!  Even though the books may appeal to teenagers because most of the characters are still in high school it works well for other fiction readers.  I have totally enjoyed reading the books.  I watched the DVD of Twlight that recently came out and you lose alot from the book.  Even though it sticks to the story line it just can't supply the same punch as reading it.
