Any cool books about erotic terror? Or something erotic with mystery or drama?

Hey everyone, I’ve been looking for books that blend erotic elements with something else... a bit of mystery, drama, or even a darker tone like erotic terror. Something that mixes the sensual with other layers of complexity.

Does anyone know of any books that fit this vibe? I’m thinking along the lines of something more intriguing than just plain erotica, where the plot, atmosphere, or characters bring in more suspense or deeper emotional layers.

Would love to hear your recommendations!
