4.5 Hard to rate a short-story in a larger story, especially if it's really more of a side-story to the fifth book. It is well-done, however, and Dr. Mensah's perspective carries with it a wholly different level of emotional involvement. What I liked especially was that we see Muderbot's humour is not all confined to pithy remarks. Also I am a sucker for stories with psychological consequences and those come across much better with Mensah's perspective.
