When Deidre Johnson fills in for Silver Bay s only police officer for six weeks, she doesn t anticipate facing anything of consequence. She is so wrong. She discovers the frozen body of a Cree Indian girl within the city limits, and in the process of her investigation uncovers a sex-trafficking ring involving native women being transported from Canada and sold in the Duluth Harbor. She is torn between the normalcy she sees around her and the long-kept secret river of young girls that flows through Two Harbors to Duluth."
