My DD #2 out of # grown and married girls, is an avid reader. She has devoured all Twilight books, seen any and everything in movies or on net about them, and named one of her kittens, "Bella". Her hubby likes them too, but not as um, I won't say obsessed, I'll just say, 'smitten'.
I have not read them, but she has told me some of the story line.
I would guess that she is an "Edward" fan, bc I don't remember her mentioning Jacob, but that was 2-3 months ago.
