Demon Hunter Severian: Lady of the Night Gates

A.D. 394. Mysterious deaths are occurring in Milan, the new capital of the Roman Empire.
The victims are from all walks of life, but have one thing in common; they all died in their sleep, unable to wake up, even to save themselves.
Is it fate or the work of a killer? Archbishop Ambrose recruits Severian, former exorcist and former soldier, a man with a tormented past if there ever was one, to shed light on the mystery and to determine if the threat they are facing is mundane or supernatural in origin.
The saga of the demon hunter known as Severian begins in this perfect mix of detective story, historical novel, and fantasy.
