The Hallow serum was once sacred to the Auld Bloods. Used to gain access to their lost ancestral powers, now it is regulated and administered by the powerful Providence Company. Evolved from the echelons of the Auld Church, the company exists to maintain the balance between faith, science and politics. But keeping the peace between humans and Auld Bloods isn’t easy. Taking Hallow comes at a price. Providence Company Assessor Cam must deal with backstreet bootleggers, burnt-out addicts and floating nuns that won’t stay on the ground. When a string of Auld Blood deaths appear to have been caused by a corrupted batch of Hallow, Cam begins to suspect all may not be as it seems. Bodies are piling up. Someone is hiding something, and the consequences are becoming monstrous.
