Her name is Grey Coltrane. She is beautiful, wealthy, sensual. But she is also far more. She has been initiated first into sex, and then into the martial arts, by a master who was everything a man could be to her. Now the world from East to West is her hunting ground, as she seeks vengeance on the monstrously powerful warrior who has taken him from her. She is no longer an apprentice in the ultimate art of violence. She is – Nightwalker. (from the back cover)
