Hugo Award-winning author Kameron Hurley's blood-soaked, inventive sci-fi/fantasy mash-up. "If you like rough, battle-scarred women who know how to regulate, you're going to love Nyx... makes Han Solo look like a boy scout." --io9 Nyx had already been to hell. One prayer more or less wouldn't make any difference... On a ravaged, contaminated world, a centuries-old holy war rages, fought by a bloody mix of mercenaries, magicians, and conscripted soldiers. Though the origins of the war are shady and complex, there's one thing everybody agrees on: There's not a chance in hell of ending it. Nyx is a former government assassin who makes a living cutting off heads for cash. But when a dubious deal between her government and an alien gene pirate goes bad, Nyx's ugly past makes her the top pick for a covert recovery. The head they want her to bring home could end the war--but at what price? The world is about to find out.
