For me too, but it was actually two novels in one book, "The Invincible" and "Solaris", and I was young back then (maybe 8yo), and didn't understand that one novel can ends in the middle of the book. Was quite puzzled about the change of topic mid-flight. My favorite book is "Wizja Lokalna", the title has been translated to English as 'Observation on the Spot' (https://en.wikipedia.org/wiki/Observation_on_the_Spot https://en.wikipedia.org/wiki/Observation_on_the_Spot). It's a wonderful allegory of problems related to the concept of the 'world of abundance' vs 'communism/authoritarianism'. The presented problems (ethico-sphere, abundance of material thing) are serious and well researched and described, even if in a humorous fashion.
