The concept of someone's life told through Yelp-like reviews intrigued me. When you think about it, sometimes reviews of something: restaurants, books, movies, etc. can tell the reader a lot about the reviewer's lives. So when the reviewer at the heart of Moody's book disappears, it sounded like an interesting idea to follow.
That said, it did not really work. Trying to tell a book through a bunch of reviews can be difficult. I read another book that was just a collection of reviews (if you remember the story of the woman who reviewed the first Olive Garden to come to her area and how that review went viral you'd know she got a book deal out of it) and did not tell a specific story. But those reviews eventually revealed the woman's life and how she used to bring friends, family, her husband (who passed away so other people began to appear in her reviews more) but that worked for what it was trying to do (it was just a collection of reviews).
This, however, does not. The book wasn't particularly readable as Morse does not come across as particularly interesting. The author tries where Morse and his paramour K. try to escape a hotel by claiming he's seriously ill (they are presented with a bill as they try to leave). But the story wasn't funny or charming and that set the tone for the rest of the book.
Based on other reviews it seems like the author had a seed of an idea but either tried to skate on his reputation or was perhaps rushed into it by the publisher. I'd skip this.
