I've just read Mr Toppit, which was dull until the last three pages. Here's what the reviewers said:
"Witty, engrossing, moving ... one hot mess of a family romance." The Times
There is no romance. It is not witty. It is not engrossing. It is not hot. And what's more, it could never be described as any of those things by someone who had read the book.
The other reviews were worse. So do reviewers just invent a book they'd like to have read?
