I have read all four of the Twilight books. I don't really like them, but I don't hate them either. They're not very good; the writing is sloppy and could use a strong edit. There are some messages in them with which I violently disagree (mainly about the lack of agency in the main female character; the way stalking is presented as romantic; the way all the women are obsessed with having babies and their lives aren't complete without them; and the way marriage is the be all and end all of life).

On the other hand, there is some excellent mocking and commentary going on around them, and I can't stop reading it. I particularly love cleolinda's (often lengthy) recaps of the books, and would recommend you read them.

I don't know that you'll really like them, but I think you might enjoy reading them in order to get more of an impact from the discussions. (Plus, if you don't like them, it helps to have read them when you debate the problems with people who like it.) I would not recommend you pay money for them if at all possible; hit the library, or other resources.

Basically, they are crap, but the mocking commentary (mocketary?) I keep reading about them is a) hilarious and b) made reading them worth it to me.
