Backwards by Rob Grant is the forth book based on the British science fiction comedy show Red Dwarf. The crew of Red Dwarf gets stranded in an alternate dimension on an alternate version of Earth where time runs in the opposite direction. Many years pass before they are able to escape this dimension and when they finally do, Red Dwarf isn't where they left it. With the limited supplies aboard their transport vessel, they must search for Red Dwarf in order to survive. This book was a fun quick read and left me wanting more. Unfortunately as of right now there are no more Red Dwarf books.
This book is an alternate sequel to Better Than Life so it picks up where that book left off and takes place parallel to Last Human. You'll definitely want to read Infinity Welcomes Careful Drivers and Better Than Life before reading this book, but it doesn't matter if you read it before or after reading Last Human. I think this book resembles the events of the show more closely than Last Human does. It was also the funnier of the two books so I enjoyed it more. I'd say that Last Human is still worth reading though even if it wasn't quite as good as this book. To anyone looking to both watch the show and read the books, I recommend watching the entire show before starting on the books because the differences between the two will be less confusing that way.
