Backwards is the fourth and final Red Dwarf novel, directly succeeding Grant Naylor-written Infinity Welcomes Careful Drivers and Better Than Life, and existing in a separate continuity from Last Human written by Doug Naylor. It is set in a fictional universe version of Earth where time moves backwards. The novel was written solely by Rob Grant and is his only solo Red Dwarf novel, Grant having previously stepped down from co-writing with Naylor for the television show after its Series VI final, Out of Time. It contains plot elements from the episodes Backwards, Dimension Jump, and Gunmen of the Apocalypse. An audiobook of Backwards was also produced, read by the author. Source: Wikipedia (en)
