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.
The City & the City by China Miéville
This had all the worst elements of the genres it tried to blend. The general concept was interesting but poor executed in all other aspects
This is the one comment that shocks me! Though I read it so long ago maybe my opinion would be different now
I agree! I loved this book and found the concept so fascinating and thought it was well executed.
