Novelette

Also spelled novelet. A term for Prose Fiction that takes the form of a very very short Novel. Is defined by the Science Fiction and Fantasy Writers of America as any work between 7500 and 17499 words. Due to their brevity, novelettes share many tropes with the Short Story but are long enough to be similar to the Novella in many respects.
