There was nothing wrong with the book and, yes, it was trolling. Writing a review in which one admits they didn’t even bother to read the book, how would you call that? And then when you check this person’s average rating and see that she gives to books in general 1 to 2 stars and does this to thousands of books per year, you know who you’re dealing with. I know a difference between criticism and trolling and I’m not going into this discussion any further. I don’t mind constructive criticism and I can sure take it. I’ve been writing since I was 10 and worked as a professional journalist for decades. Goodreads, however, became notorious for trolling and they do nothing to stop it.
