I bought this for my 14yr old niece, who has been to all the vampire movies, read all the books, worn all the t-shirts. It took her only 2 days to read it all the first time, and it got a huge thumbs up! She says the information in it allowed her to understand some of the things she has read/seen, and a lot of it was new to her. I want to read it too but I have to stand in line behind her girlfriends.If you know any teenage girls definitely put this book on your ‘to buy’ list, they will love you forever…or at least until the next fad comes along!
