Query: Mills is a writer who shows promise

Compelling thriller which takes us into the mysterious world of cults and the good and evil forces that underlie their success. FBI agent Mark Beamon is not your typical action book hero. He's an overweight, beer drinking, unlucky in love man who happens to be an extraordinary investigator with an unselfish drive to solve crimes and seek justice. His no-nonsense ways and refusal to play by the rules causes him to catch a lot of heat from his superiors. However, Beamon realizes that he is racing the clock to find a missing teenager girl whose parents were brutally executed and who may be facing the same fate herself. With little to gain and much to lose, Beamon takes off on a hunt that leaves the bodies piling up and his own life hanging by a thread.
