'Myfanwy Thomas returns to clinch an alliance between two deadly rivals, and avert epic - and slimy - supernatural war such as the world has never known.

'After years of enmity and bloodshed, two secret organisations with otherworldly abilities must merge, and there is only one person with the fearsome powers - and bureaucratic finesse - to get the job done. Rook Myfanwy Thomas must broker a deal between deadly rivals the Checquy - a centuries-old covert British organization that protects society from supernatural threats; and the Grafters - a centuries-old supernatural threat.

'But an assassination attempt threatens to derail the whole process, and Myfanwy must dispatch two young agents - one from each side - to track down an extremist faction and destroy it before a devastating war is triggered.'
