Popular Culture Mashup novel

A mash-up novel (also called "mashup" or "mashed-up novel") is an unauthorised non-canonical (and not even in-universe) work of fiction (often parody) which combines a pre-existing literature text, often a classic work of fiction, with another genre, usually horror genre, into a single narrative. Marjorie Kehe of the Christian Science Monitor renders this admixture of classic text as "somewhere between 60 and 85 percent original text, with new plot twists added by contemporary co-authors".[1] These "twists" often include horror fiction elements like vampires, werewolves or zombies.
