Tressa Norne is an American living in China.  After her life was spared during a revolution in the area, Tressa finds herself taken as a slave and forced to serve Erlik, a demon-god, and his cult.  She ends up escaping back to America, but only to find that she is being followed by the Secret Service, and her former masters.  (Ann Boulais)
