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.
A Question of Travel by Yvonne de Kretser. It’s a shame as I loved the first third but it promised much and delivered little. I came to dislike the female protagonist so much. The male I liked. We follow these two separate stories for 500 pages expecting them to come together and they do, but barely and with no significance, and then the book is over.
