Can you recommend me some very sexy, high tension, unhinged good plot, not sappy books? Yes I tried to post in romance books and it didn’t work

I really really don't like sweet/tender things in books and I don't love tragic ends to love stories – moreso unexpected twists and turns, a journey of chaos and intrigue (cheating, taboo, etc.) plus an ending that doesn't tie everything in a nice little bow at the end

Please help & thank you

(Loved All Fours, Normal People and Big Swiss for context)
