John Gaunt, Doctor of Angelology, walks a fine line between Policeman and Priest.
As a Wing Clipper, a police officer dedicated to hunting rogue Angels, he is accustomed to the bizarre.
In the city of Edenburgh, Wing Clippers are being murdered, Angels are being crucified, and girls are going missing, sold into slavery and forced to break the oldest taboo of all.
Hunting the shadowy terrorist organisation The Black Spire, Gaunt begins to realise that there is a dark secret to the world he lives in.
When that darkness is visited upon his own family, he must ask the question...
When Angels kill your wife and steal your child, who do you pray to for revenge?
