I set the flare as romance but to could lean more towards horror as well. I want something that has actual female monsters seeking out our male main character for either nefarious purposes or out of romantic interests. When I say monsters, I don't just mean humanoid women with animal ears, weirdly colored skin, or fangs, I mean like Eldritch horrors, abominations, and beings that'll make you question reality or even the narrator's sanity when they describe them.
Imagica by Clive Barker might be a good example of what I'm looking for, books reminiscent of that.
