Ancillary Sword (Imperial Radch)

The sequel to Ancillary Justice, the only novel to ever win the Hugo, Nebula, and Arthur C. Clarke Awards and the second book in Ann Leckie's New York Times bestselling series.
Breq is a soldier who used to be a warship. Once a weapon of conquest controlling thousands of minds, now she has only a single body and serves the emperor.
With a new ship and a troublesome crew, Breq is ordered to go to the only place in the galaxy she would agree to go: to Athoek Station to protect the family of a lieutenant she once knew - a lieutenant she murdered in cold blood.
