On authors and categories and confusion

Well, I can't say that I never read romance novels, because that would be a complete lie. I certainly don't consider myself too good to read them, or anything else for that matter. Those of you who know me know that I read almost anything that comes along. And, in need of a book, a formulaic romance is as time killing as anything and requires no real mental effort.
I also read the same book over again, sometimes because I re-bought it in a new cover (Argh - there is a book budget after all!!) and sometimes because it happens to be handy and I DON'T HAVE A BOOK! That is the real crux of things, not having a book can be critical in a lot of situations, like every time there's a waiting room involved.
However, the point of this little diatribe is that I found a perfectly lovely little novel at Third Place Books on the SF/Fantasy cart that had a little magic, a little more lust than necessary, but not gagging, and some quality of story (that means I wanted to finish it, as opposed to not caring).
Soooo, I went looking at Half Price ( I know, but it's close and I was just looking) for some more by the same author, and got an bit of new information. There is (maybe nowhere else) a category called "Paranormal Romance", I mean shelf labels and everything, a whole row! I was stunned.
I did discover that most of them involved vampires which is probably why I've not been in that area before, and the only other volume that they had by the author I was looking for was #3 in another series.
Oh well, it's a long weekend, I may get to Third Place or Village Books.
