I have two. The Ritual and Drowning.
The Ritual is pure smut. 61 chapters and every one contains a graphic, demeaning sex scene. I’m convinced the author was an adult film screenwriter and decided to try their hand at writing a novel. There isn’t a single likable character in this book.
Drowning isn’t a great work of literature. I felt that the characters were very two-dimensional. I hated how naive the author made the protagonist. It made me have a lack of sympathy for her. The ending was series finale of Dexter bad.
Spellmonger.
It starts off okay, then shoehorns some sex in and you’re like “huh, okay, glad that’s over”. Then sex magic gets introduced. At length. Then a short while later the main character has an incestuous threesome with a 16 year old.
At this point I complained to my brother who recommended it to me. He was like “oh yeah I guess the beginning is bad, but that’s all done now.” Apparently he forgot that exciting conclusion involves the main character saving everybody through the magical power of exhibitionism.
I stopped reading it 20 pages from the end. I just couldn’t stand it anymore.
