Toxic romance request
My pet rock business is booming and I have money to throw into books once again. Please suggest your darkest, most poisonous, most toxic romance books/series below.
Anything with an interesting setting is more than welcome!
Any sex level is fine, though I prefer it when the book is not just a fuckfest back to back. Dark themes, horror, yandere are all welcome!
(pls no furry. I have fur allergy)
(and also please no LitRPG)
Thanks in advance!
