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 eventually loved the book, but I don’t think it establishes Red and Blue as enemies/rivals well enough in the beginning. I enjoy the relationship but it happens simultaneously very fast and very slow – I’m a bit of a lazy reader and generally need more story along with the prose (which I did find beautiful.)
