Facing annihilation at the hands of the warlike Vogons, Arthur Dent hurtles through space powered by pure improbability and is desperately in search of a place to eat. Among Arthur's shipmates are Ford Prefect, a long-time friend and contributor to the The Hitch Hiker's Guide to the Galaxy; Zaphod Beeblebrox, the three-armed, two-headed ex-president of the galaxy; Tricia McMilan, a fellow Earth refuge who's gone native (her new name is Trillian); and Marvin, who suffers nothing and no one gladly. This is the sequel to The Hitchhiker's Guide to the Galaxy.
