The Restaurant at the End of the Universe by Douglas Adams

alternate edition for ISBN 0345418921/9780345418920 Facing annihilation at the hands of the warlike Vogons is a curious time to have a cosmically displaced Arthur Dent and his curious comrades in arms as they hurtle through space powered by pure improbability - and desperately in search of a place to eat. Among Arthur's motley 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 name is Trillian now); and Marvin, who suffers nothing and no one gladly.
