The Oversight is most dangerous when most reduced. There are many dead and gone who did not remember that. The Oversight of London has been sworn for millennia to prevent the natural and the supernatural worlds from preying on each other. Now at its lowest ebb, with its headquarters destroyed and its last members scattered far and wide, this secret society will battle for survival and face the harshest foe it has ever met: itself. Exciting, exhilarating, scary and moving in equal measure, The Oversight is a teeming world of dark deeds and dark magics, brilliantly realised - M. R. Carey on The Oversight
