Red Dwarf (often referred to as Infinity Welcomes Careful Drivers to differentiate from the television series) is a book written by Rob Grant and Doug Naylor and published in 1989, and is based on the first two series of the sci-fi comedy television show Red Dwarf. Its main feature is that it gives the reader a much deeper insight into the characters of Lister and Rimmer than the television series, and also gives a lot of background information about the human race at the time of Red Dwarf. It contains scenes and elements from the episodes The End, Future Echoes, Kryten, Me² and Better Than Life.
