Monster FMC

Looking for a romance (sub category doesn't matter), with an FMC who is a monster. The type of monster thats hideous, scary, terrible, etc. And an MMC that's human or human adjacent. I just read Frankenstien and went down a Frankenstien and bride of Frankenstien rabbit hole and now I am here, realizing most monster books and stories are written with the man being the monster! I want the reverse! I looked up other lists and recs on reddit but the books they mainly suggested were just FMC's who weren't human, and I want an actual monster monster. Thank you in advance!
