Ancillary sword - Ann Leckie

Ancillary Sword is the sequel to Ancillary Justice, the debut which is the only novel to ever win the Hugo, the Nebula and the Arthur C. Clarke Award.

Breq is a soldier who used to be a warship. Once a weapon of conquest controlling thousands of minds, now she only has a single body and serves the emperor she swore to destroy.
Given a new ship and a troublesome crew, Breq is ordered to the only place in the galaxy she will agree to go: to Athoek station, to protect the family of a lieutenant she once knew - a lieutenant she murdered in cold blood.

The Imperial Radch trilogy begins with Ancillary Justice, continues in Ancillary Sword and concludes with Ancillary Mercy.
Also available now: Provenance is a stunning standalone adventure set in the same world as Ancillary Justice. NPR calls it 'A fitting addition to the Ancillary world'.
