The justice system failed her family—and so did her hometown. Madison Colson knows deep down that her father—a convicted serial killer—is innocent. But believing it and proving it are two entirely different things. Unable to help her father, Madison has spent most of her adult life overcompensating by helping others. When her aunt dies unexpectantly, duty calls her back to Fog Lake, Tennessee, a beautiful but painful place she’d rather forget. Terrifying events begin to unfold once she arrives, unleashing her worst nightmares. The Good Samaritan Killer—or a copycat—is back, and now Madison Colson is his target. FBI Special Agent Shane Townsend is determined to stop the deadly rampage that has sent the tightknit community into a frenzy. But he needs to earn Madison’s trust first. The task feels impossible, especially considering his father is the one who put her dad in prison. With the whole town on edge and pointing fingers, tension escalates out of control. Madison and Shane must sort the facts from the lies—and fight for a legacy of truth—before The Good Samaritan Killer has the final say.
