This is someting that has bothered me for a long time. Why are people so obsessed about categories? If you want to make a fantasy story, that's fine. But does that mean you have to stick to the "rules" and only include things that's "legal" in fantasy? If you are writing a horror novel, is it wrong to include comedy? I have been to several forums over the years, and people on every single writer's forum I've been to ask the same questions: "What cateogry is my book?" or "What category should I write?" Every time. And every time, I end up saying the same thing. "Does it matter?" If you think about it, a category like horror, romance, fantasy, sci-fi etc is meant to be a good thing as it can be easier for the reader to find a book he/she wants, but to writers, it only holds us back. As a great example, think about Frank Herbert's Dune. Back when it was written, sci-fi were nothing but spaceships, laserguns, aliens and all that. Not many took it seriously, and many said it wasn't supposed to be serious. But when Dune was relesaed, it changed sci-fi forever and was rated as good as Dostojevski and those guys. The fun thing is Dune isn't a sci-fi novel at all. True, it takes place on another world in a fictional universe with sci-fi technology and all that, so it had a lot of sci-fi elements. But the core story isn't sci-fi at all, but a character based drama worthy of Dostojevski and Shakespear. And that's the point. If you want to write a story, write the story. It doesn't matter what category or genre it is. If it doesn't fit into one, it might fit into another. But if it doesn't fit into either, you have created a third one and given the rest of us a new category to place our books in. It might seem stupid, but Dan Brown helped kickstart the "historical mystery" books with "Angels and demons" and "The DaVinci Code", though people like Indiana Jones and Lara Croft (Tomb Raider) did a much better job. These days Dan Brown is just a sidenote in the big picture, with countless better writers writing in the same genre as him. The same goes for Twilight. How many teen-vampire-romance novels did you know before Twilight, and how many do you know now? So in a way, teen-vampire-romance is now a category on it's own alongside romance, drama, horror and all that, and it keeps evolving all the time into other categories. Teen-werewolf-romance, for instance. My point is don't worry too much about a category. A category is just so the reader know what to look for. Nothing more, nothing less. And breaking barriers and thinking outside the box is actually helping with that. The more categories we have, the easier it is to narrow it down to the one we want. Ir just create a new one.
