Classic sci-fi if you’re into that thing. Asimov is a good storyteller, but he can get a bit technical. I love this, but I also thing that not everyone may appreciates it. This particular book completes the robot series and really delves into the subtleties of the Three Laws(Three Laws of Robotics). Specifically, I found it fascinating to read about a culture on Aurora where robots enjoyed a higher status and a stronger Third Law. You can see the evolution of their design that would eventually lead to the emergence of the Zeroth Law.
