Query: Enjoyable, Entertaining, and Fast Read.

As many have said, this is not a horror story, it is a love story. However, the story reaches bridges the gap of young adult to mature audiences. I would feel comfortable reading this book to my 10 year old daughter. The 500+ pages go by extremely fast, and leave the reader wanting more. In fact I just finished book 4 which is 753pages in one day. The novels are gripping, dramatic and emotional. I highly recommend them to anyone ages 10-100 male or female and PLEASE don't be discouraged by the size of the book.
