1) nothing wrong with sex in books, but considering the quality of her writing these days, I'd just rather buy an erotica anthology instead if that was important to me.

2) To a point, sure, but I think it relates to possible mental illness. I won't deny that writers do attached to what fictional people they write about, but even some children's authors aren't afraid to kill of some important people, wether or not they are attatched to them. Basicly, I think it's a sign she needs therapy, or at the very least, a long break from writing.
