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.
Cleopatra and Frankenstein. Every character was pretentious and insufferable and they kept stressing just how young and teenager-like the fmc looked. Maybe this is part of a storyline where her male love interest turns out to be a p*do or something, but I’ll never know because I DNF’ed.
