Surreal, but a bit jumbled. I liked it, but could have been a short story.

The topic discussed the most was the topic of cheating the systems' constraints and the backlash of consequences.

It's somewhere between 3¹/₂ and 4, but I'm giving it 4 because it is seriously underrated. Of course, it's less of a banger compared to the first book, but there's no need to go Gentle Giant fan on it.

Gentle Giant was a British progressive rock band that released a number of albums so novel and captivating, almost nobody have understood them. But those who did, at least to a degree, got very upset when they have started making music that was just good, if not a little poppy. It led to the bands eventual demise.

Granted, Douglas Adams neither cares, nor cared for the people calling his works "rambling" or his thinking too shallow (or indeed too deep, by those boasting about their ignorance), I still feel it would be a bit unfair to reduce the overall rating of the book by rating it as 3.5.
