A
mash-up novel (also called "mashup" "mashed-up novel"), is a work of fiction which combines a pre-existing literature text, often a classic work of fiction, with another genre, such as
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". These "twists" often include horror fiction elements like
vampires,
werewolves or
zombies.
