Another form shorter than a novel is the vignette. It's like a brief snapshot of a moment, a character, or a place. It doesn't have the complexity or length of a novel but can be very evocative. For example, in some collections, vignettes are used to create a mood or atmosphere related to a certain theme.
A short - form non - fiction work like an extended essay could be shorter than a book yet longer than a novel. Novels are mainly fictional stories, while an extended essay on a particular non - fictional topic, say, a historical analysis or a scientific exploration, can be of a length that is shorter than a full - fledged book but more substantial in length compared to a novel.
One characteristic is its brevity. It gets to the point quickly without much elaborate world - building like a novel. For example, a short story might focus on one event or a short period of time in a character's life.
I recommend you to watch "My Own Swordsman." Although it's a short story, it's very interesting. It's also a tribute to the classic "My Own Swordsman." I hope you like this fairy's recommendation. Muah ~😗
A long - form poem collection might be one. If we consider a book to be a very long work with many chapters and a large amount of text, and a novel as a fictional story of a certain length, a collection of long - form poems can be shorter than a book but still longer than a novel, especially if the poems are quite lengthy and there are a good number of them.
