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.
Well I wanted to leave a Amazon review saying how horrid it was and I found 1000’s of positive reviews that I assume were created by bots that seemed cookie cutter/cut and paste. Each review was was almost the same with line like” the best book ever” and “my favorite fantasy book ever”. I just went back to find some disposable examples and now they are so buried by real people with bad taste that I cannot find any fake reviews.
