The Nightpath Trilogy continues as old grudges come calling, with hell to pay. It's been a year since Eskander and company saved the underraces of San Francisco from certain annihilation, and the spymaster has been working diligently for King Thog'run of Aurichome, who happens to offer great dental. A new threat appears as old grudges rear their ugly heads, forcing the former NIGHT agent and his companions to contend with a powerful form of wizardry that bridges magic with machinery: Technomancy.
