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 author literally destroyed your trust in his ability. That’s exactly what happens. Always call it what it is, it IS a betrayal of trust. A lot of ‘authors’ don’t respect their readers’ time. And, a lot of their ‘reviews’ are paid to be five star. I always read one and two star reviews for this reason specifically: did this author betray a reader’s trust that they could tell a satisfying story?
