As the first novel to ever win the Hugo, Nebula, and Arthur C. Clarke awards in the same year, it’s no stretch to call Ann Leckie’s debut space opera Ancillary Justice (Orbit, 2013) a phenomenon. While you’re waiting for the sequel, Ancillary Sword, please enjoy this reprint of “Night’s Slow Poison,” a short story by Ann Leckie from the world of the Imperial Radch. “Night’s Slow Poison” is a rich, claustrophobic story of a galactic voyage that forces one guardsmen to confront his uneasy family history through the lens of a passenger with his lost lover’s eyes.
