I'm sorry to say that this one did not have an audio version read by Chris Barrie so I stuck with the written edition. Maybe it was the lack of Chris or maybe that Grant does need Naylor to balance him but I wasn't as happy with this outing.I don't think I minded that there were less laughs and some of the humour was darker. What I did mind was that living backwards just couldn't sustain the concept for an entire book. I still laughed and enjoyed it but just not near as much as the first two. I also missed the Cat. He seemed to be MIA for a good portion of the book.
