Running on Empty - Gregory S. Hudson - Bog

As the Lucas Twins serial killers secretly terrorize the lives of nearly 100 victims, there are two victims that escaped. One escaped certain death in 1979 and another escaped 40 years later. Fate brings the two together as they realize their lives have been mentally and psychology ruined by the same people. They embark on a journey to find their tormentors only to have many other secrets revealed. The world of a supernatural being is discovered along with a bizarre ritual that keeps the twins hungry for more victims even as they reach their 70s. Revenge is best served cold. 40 years is definitely cold enough. Now is the time for justice to be served.
