Arthur, Ford, Zaphod, and Trillian continue their absurd journey through time and space, visiting Milliways—the restaurant at the literally apocalyptic end of the universe—while Zaphod pursues the man who rules the universe and Arthur and Ford accidentally end up stranded on prehistoric Earth. More episodic than its predecessor but equally committed to comic invention and satirical irreverence. The series hits its satirical peak in the middle books.
