Well DD12 read them just to see what all the hub bub was about but greatly disliked them. Her issues were (and I quote from an email she wrote and copied me on):
"They sound like a 10 year old wrote them--especially the first two"
"It is really creepy that the book goes on and one about how wonderful some guy who stalks her and even sneaks into her room at night is. That is not romantic; it is really, really wrong. And Bella only loves him because he is so good looking and pale and cold which we get told on almost every page AND becuase he tells her that he feels constantly compelled to kill her but doesn't becuase he loves her. I don't think that is romantic, I just think it is sick."
The friends she has who are not allowed to read them either becuase they deal with the supernatural OR becuase eventually the characters do have sex (they are married by then and it is not even remotely graphic--basically they go to bed and wake up the next morning with the room torn up

).
