Ancillary Mercy (Imperial Radch, Book #3) by Ann Leckie
Breq and her crew must stand against an old and powerful enemy, the Lord of the Radch, and fight for the right to determine their own destinies in the stunning conclusion to the NYT bestselling Imperial Radch trilogy A must read for fans of Ursula K. Le Guin and James S. A. Corey.
Winner of the Locus Award for Best Science Fiction Novel 2016
For a moment, things seemed to be under control for Breq, the soldier who used to be a warship. Then a search of Athoek Station's slums turns up someone who shouldn't exist, and a messenger from the mysterious Presger empire arrives, as does Breq's enemy, the divided and quite possibly insane Anaander Mianaai - ruler of an empire at war with itself.
Breq refuses to flee with her ship and crew, because that would leave the people of Athoek in terrible danger. The odds aren't good, but that's never stopped her before.
