A young woman saved from freezing to death and drowning in the icy Black Root River outside a small Minnesota town learns her and her friend's accident was anything but, and that she has a personal connection to a similar young woman who lost her life in the same river ten years earlier--and the killer may have just tried to strike again. Determined to get answer, the woman plunges into her own investigation, and uncovers a secret history of violence that, if brought to light, could destroy her hometown.
