What is it called when someone writes a prequel to a book, but it's a short story? It's a like a story that happened before a normal sized book, but instead of the prequel being a full sized book too, it's a short story? Like, say if I write a normal sized book, and then wrote a prequel that's way smaller, what would it be called? Is there a name for it? Will give brainly for anyone who answers correctly.
