This one is even better than the first two. Murderbot thought it just wanted to be left alone and to watch media, but decides it needs to help out Dr. Mensah with her case against GrayCris. And suddenly it's impersonating a security consultant and a SecUnit at the same time, hacking and controlling multiple bots at once while keeping watch for betrayal - it's nonstop action for the reader. And such an emotional hit at the end! This is such a great little series.
