Shadow hunters

A serial killer is at large in Thailand.  The victims are seemingly picked at random.  The killer leaves behind no forensic evidence.  The Police are at a loss. 
 
An ex-Buddhist Monk, Khun Phanom Siriat, has been having visions related to the killings.  A female office worker in Bangkok, Khun Ariceya Yonkhamsean, has been having dreams that she believes are somehow connected to the killings.  The couple find that their destiny is entwined as Phanom saves Ariceya from becoming the killers next victim. Together, they set about investigating these brutal slayings. 
 
How are these murders related to events that happened 3000 years ago?  Has an ancient prophesy been set in motion?  Phanom and Ariceya become involved in supernatural events that lead them on a chase throughout Thailand.  In a race against time there will be only one winner, life or death!
