Spearpoint, the final human city, can be an atmosphere-piercing spire of huge size. Clinging to its epidermis are the areas, some semi-autonomous city-states, each which likes a different-and rigidly enforced-level of technology.

Pursuing an infiltration mission that went tragically wrong, Quillon continues to be living incognito, working like a pathologist in the district morgue. However when a near-dead angel drops onto his dissecting desk, Quillon’s world is wrenched apart one more time. If Quillon is to save lots of his life, he must keep his house and journey in to the cold and hostile lands beyond Spearpoint’s bottom, beginning an exile which will take him further than he could ever imagine. But there is far more at stake than simply Quillon’s own survival, for the restricting technologies of the zones are determined not really by government authorities or law enforcement but by the nature of reality-and truth itself is displaying worrying signals of instability.
