These stories sometimes read more like a short story and sometimes more like a novel. Novelette is any short, fictional work of prose narrative. Novelettes have a lower number of words than a novel or novella, but a higher word count than other forms of prose fiction like short stories or microfiction.
While, Novel is only considered when the story or stories (such as a collection of short stories) is written in no less than 40,000 words. Novels should only consist of stories.
