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.
Bram Stoker’s Dracula. The book itself isn’t that bad, at least not the part I’ve read. But my German edition has more spelling mistakes than all of my other books combined. Unfortunately, I bought it second hand. Otherwise I would’ve returned it.
