If Ancillary Justice was a fascinating tour in non-linear exposition, and Ancillary Sword felt like a cozy mystery set in the midst of a space opera, Ancillary Mercy struck me as an interstellar version of the folktale motif “six go through the world”. That is, a protagonist accumulates a set of unlikely and improbable allies simply due to treating those she encounters with honesty, empathy, and (if you will forgive the word) humanity, to find that those allies come through with a vengeance when the chips are down.
