For those who have not read it, let me say that there are some positive aspects of this book, particularly considering what else is out there to read.
The vampire who Bella loves is part of a group of vampires who "abstain" from drinking the blood or killing humans, although they instinctively desire to do so. They abstain for moral reasons. Instead they go on regular hunting trips and kill animals. The concept is kind of gruesome but I like the metaphor that can be applied to human sexuality. Control, limitation, etc. The notion of resisting temptation for the greater good is quite positive.
Still, Edward makes it clear to Bella that he does not know how well he can control himself. Fair enough. But Bella continues to put herself in situations of isolation with him that are risky for both of them. He grows in his confidence to control himself but still indicates that there is a danger. (Another good parallel to the struggle to remain chaste.)
But in Bella's case we're talking about a life-threatening risk and she justifies her decisions on the basis of love. As a mother I am therefore concerned about the model of Bella's judgement. Also, what is described as love, at least at first, really seems to be nothing more than physical attraction. OK. Many love relationships begin with physical attraction.
It was this risk that Bella takes that led me to tell my daughter that risky men are not good guys to date (when she starts dating.) Good common sense should override physical attraction. "Bad boys" are not good!
Because of the curious story line though the lesson is a little confusing. Edward tries quite successfully to be good. He is very committed to Bella's safety. Still, they take risks.
He often sleeps with her in her bed!!! Chastely, mind you. While the book is VERY sensual there really is no sexual content. They kiss occasionally.
My message to Mary: It is a very bad idea to lie in the same bed with a guy you really, really like. It's a very bad idea. It is almost always an occasion of sin. Men are not vampires and he is not going to stay awake all night just enjoying looking at your face. NOT going to happen.
I guess the concern as a mom is that young people might think they can withstand temptation and do this kind of thing.
