I see it a lot in the books and novels section. There are a lot of subcategories too so their probably is a creative writing category. If your story pretains to another topic on hubpages you might want to try and put it in that category and see if it gets read because there is so much fiction and poetry it might get lost. You can also change the category you put stuff in after you post it. I have a lot of hubs that can go in more than one category and I have changed them around a bit here and there.
