Love Murderbot, but once again sad the novellas are so short. This fourth novella brings the series to a close (but with rumours of a full length novel coming probably around 2020 - yay). It wraps up the loose ends reasonably well; Murderbot saves the day (and Dr. Mensah) again; and lots of snarky Murderbot commentary along the way. First novella is still the best however, if only for the refreshing newness of the characters.
