After finding evidence proving that the GrayCris Corporation engaged in illegal activities, Murderbot heads out to hand the case over to Dr. Mensah, its former owner. But Dr. Mensah has disappeared, and Murderbot must track her down—straight into the heart of enemy territory. Saving its mentor and taking down GrayCris are just the beginning of its challenges—Murderbot also has to figure out who it is, where it fits in society, and just how it is supposed to relate to all these people. The fourth installment of Wells’ Murderbot Diaries (after Rogue Protocol, 2018) will satisfy readers’ hopes for this series finale. It follows the same basic structural formula as its predecessors, so it has all the action fans expect. Exit Strategy tones down the humor a bit but adds depth to Murderbot’s introspection as it wrestles with questions of identity that it has been avoiding, and the story leaves it to decide its own future. Everything comes full circle while remaining appropriately open ended. Wells gives us a worthy conclusion to one of the best series in recent memory.
