If you like Tchaikovsky, this is another book from him! A valet-model high end robot finds that he has killed his master. And then it turns out this appears to be part of some overall societal collapse. Finding answers isn’t really part of the robot’s programming, but not being able to find another human who he can serve is a problem. He goes out looking for another one and finds a lot of deep dysfunction (and maybe a friend) in this occasionally humorous dystopia.
