Less happens in this, the fourth book of the Hitchhiker's trilogy, than in the preceding three, but it is funny and clever in true Adams' style. The story includes a new Earth and a love interest for Arthur Dent (one that sends them soaring into the clouds). Three bowls gifted by the missing dolphins, an inside-out house in California, the co-ordinates to God's final message, a grumpy rain god and angels in Scholl sandals provide the requisite whimsy and allow the reader it indulge in a much needed escape from reality. It's silly and fun (as you'd expect) but perhaps not quite at the level of other Adams novels. Suspense and conflict are absent, replaced by convenient coincidences that allow Arthur to sail gently through the story.
