Detective Ryan O'Clery is working a series of homicides when he discovers a journal kept by an uncle five generations earlier, detailing the same type of murders as the Night of the Big Wind swept the Atlantic Ocean across Ireland in 1839. As Hurricane Irene barrels toward the North Carolina coastline, Ryan discovers even the killer's description matches exactly.
Detective Ryan O'Clery agrees to meet a noted historian claiming to have discovered information about his ancestors, but when he arrives he finds her murdered and her computer stolen. His investigation will lead him back to 12th century Ireland, to a time of Viking invaders and conquests, to an albino known as The White Devil of Dublin, and to a secret his family kept hidden for more than 800 years. It will also bring him face to face with a serial killer intent on finishing the job he started.
