God’s War 

Nyx had already been to hell. One prayer more or less wouldnt 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, theres one thing everybody agrees on—Theres 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, Nyxs 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.
