Mackenzie Anderson’s husband and two-year old daughter were shot and killed when Mack was only nineteen years old. When the police stopped trying to find the murderer, Mack began working with a private investigator. But, the murderer was a ghost. Mack had no way of knowing then that in a fluke of life she would come face-to-face with the murderer six years later. Now, she must decide if she will risk everything for vengeance.
As a homicide detective with the Idaho State Police, Mack lives her life being a champion for the dead. Assigned as the lead investigator of a triple homicide that occurred in the picturesque, small Idaho town of Skaus Lake, Mack befriends Susan, a teenage girl who is the daughter and sister of two of the homicide victims. Three weeks into the investigation, a man strolls into the police department and confesses to the homicides. But, something about the case continues to nag at Mack.
