I like certain subgenres within science fiction and fantasy, and one of those is urban fantasy, and another is steampunk.
As for genre, my adult books are usually filed under science fiction / fantasy, although some stores put them into romance, and few have stuck them into horror. I consider all my books a mix of steampunk and urban fantasy.
To me, steampunk and urban fantasy are naturally hinged together. And I think that's because I love the early gothic Victorian literature, and both things spring from that movement.
