Exit Strategy

 Exit Strategy (#1,060) is the fourth and supposedly final book in Martha Wells' entertaining sci-fi Murderbot Series.  But Huzzah!  We know from checking on Fantastic Fiction that there are more books out there!

The protagonist is a SecUnit - a combination robot designed to protect whoever has contracted for its services from harm.  It does have some human features, but its mission is so focused on security that SecUnits cannot travel or act or their own: their responses are programmed into them.  Unless, of course, you happen to be the SecUnit who has managed to hack its own governor and christened itself Murderbot.  It isn't easy, but Murderbot does manage to save the day and expose the bad guys in some nail-biting action.  And perhaps Murderbot has been more influenced by its human components than it originally realized (or likes!).

Exit Strategy closes the story arc in the previous three novellas, so don't try to read Exit Strategy without reading the books first.  Trust me, it won't take long!  What a great read!
