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.
I am totally ok with books that have no plot, but The Night Circus’s problem was that it had no plot or characterization. The characters were so flat and I could not force myself to give a shit about them. It was the best example of an all vibes book I can think of and taught me that I do not like books that are all vibes lol
