Jeff Kinney had far been one of the greatest children's authors, and one of my favourite. But this time, after 12 whole books with great and relatable tales, it is officially declared that Jeff Kinney is running out of ideas. He keeps repeating details from his other books, and the story doesn't revolve around a certain point, and doesn't seem as extreme and thrilling like the other books. As far as I'm concerned, I say that this is one of the worst books he had written. It would be better to read the previous 12 books.
