On the subject of romance: I love romance as a subplot. I would say at least half of my novels, if not most, include a couple or some kind of romantic storyline. It's just not usually the MAIN plot; there's usually something else, like a terminal illness or a mystery to solve or zombies, that takes center stage while the love story develops on the side.
You all know I love writing medical stuff and killing people. What I don't enjoy writing is the music business stuff, but it's kind of a necessity at times in our fandom, unless you only write AU. I just don't feel like I know very much about the business side of things and find that harder to research in order to write it realistically. I'm also not comfortable writing fantasy, where you have to create your own world and laws for that world that made sense. I admire people who have the creativity to do that!
