"When two secret organization are forced to merge after years of enmity and bloodshed, only one person has the fearsome powers -- and the bureaucratic finesse -- to get the job done. Rook Myfanwy Thomas must broker a deal between two bitter adversaries: the Checquy, a centuries-old cover organization that protects Britain from supernatural threats, and... the Grafters, a supernatural threat. But as bizarre attacks sweep London and threaten negotiations, old hatreds flare. Surrounded by spies, only Myfanwy and two women who absolutely loathe each other can seek out the culprits before they trigger a devestating otherworldly war." --P.4 of cover.
