Ancillary Justice is a science fiction novel by the American writer Ann Leckie, published in 2013. It is Leckie's debut novel and the first in her Imperial Radch space opera trilogy, followed by Ancillary Sword (2014) and Ancillary Mercy (2015). The novel follows Breq—who is both the sole survivor of a starship destroyed by treachery and the vessel of that ship's artificial consciousness—as she seeks revenge against the ruler of her civilization. The cover art is by John Harris.
Ancillary Justice received critical praise and won the Hugo Award,[1] Nebula Award, BSFA Award, Arthur C. Clarke Award, and Locus Award for Best First Novel. It is the only novel to have won the Hugo, Nebula, and Arthur C. Clarke awards.[2]
Two other novels, Provenance (2017) and Translation State (2023), and two short stories, "Night's Slow Poison" and "She Commands Me and I Obey", are set in the same fictional universe.[3][4]
