The first lesson Lister learned about space travel was you should never try it. But Lister didn't have a choice. All he remembered was going on a birthday celebration pub crawl through London. When he came to his senses again, with nothing in his pockets but a passport in the name of Emily Berkenstein.

So he did the only thing he could. Amazed to discover they would actually hire him, he joined the space corps----and found himself aboard Red Dwarf, a spaceship as big as a small city that, six or seven years from now, would get him back to Earth. What Lister couldn't forsee was that he'd inadvertently signed up for a one--way jaunt three million years into the future---a future which would see him the last living member of the human race, with only a hologram crew mate and a highly evolved cat for company. Of course, that was before the ship broke the light barrier and things began to get really weird...


Better than Life

A wild and wacky SF series--based on the popular BBC-TV series--reminiscent of The Hitchhiker's Guide to the Galaxy. Lister--who passed out drunk in London and awakened in a locker on a moon of Saturn--now finds himself trapped in a computer game that transports players to the perfect world of their imaginations--a game people are literally dying to play.
