Monster Romance

A monster romance is a paranormal or fantasy romance (often "spicy") novel with at least one monster main character. 

Examples include orcs, lake monsters, minotaurs, and krakens, but the sky is the limit when it comes to monsters. Virtually every folkloric tradition includes monsters, so when in doubt, dive into the fables and tall tales from a given culture and discover the possibilities for things that go bump in the night.
