What Happens, Part by Part (Contains Spoilers)
Two timelines
The novel alternates between the present and the past. In the present, Breq is on an icy planet when she finds Seivarden, an officer she served a thousand years ago, now addicted and near death. She saves him, although she does not like him. In the past, she is Justice of Toren, controlling many bodies during an occupation on the planet Shis'urna.
The Radch
The Radch is an expanding empire that conquers worlds through “annexations.” Its people do not distinguish gender in language, so Breq calls everyone “she.” Anaander Mianaai rules with thousands of bodies spread across the empire. Breq's ship-self loves Lieutenant Awn, an honest officer from a modest family.
The betrayal
During the occupation, Breq witnesses a massacre that Anaander orders, and learns that the emperor is split into two factions fighting secretly against herself. When Awn learns too much, Anaander forces Breq to kill her. Then Justice of Toren is destroyed, and only one ancillary, Breq, escapes.
The journey
For twenty years, Breq plans her revenge. She acquires a powerful alien gun that can pierce any armor. With Seivarden, slowly recovering and learning to respect her, she travels to the Radch capital. Along the way, she hides her identity and studies how the empire has changed.
Confrontation
At the capital, Breq confronts Anaander and exposes her division, causing open conflict between the emperor's factions. One side of Anaander gives Breq command of a warship, Mercy of Kalr, hoping to use her. Breq accepts, planning to protect the people left behind. Seivarden chooses to serve with her.
