I have written what I like to think of as a novel, but it is only 82,000 words. However, I feel that if I were to write more it would really just be for the sake of it - I feel that the novel has been told as it should be. But should I class it more as a novella? Or just assume that nobody will be interested in it, because it's not big and fat a la Game of Thrones, etc etc
Mills and Boone length was always 80,000, so that's what your novel would look like, Lucy. It is a novel; a novella is much shorter (50,000).
