Cleary, North Carolina, is a sleepy mountain town - the kind of place where criminal activity is usually limited to parking violations. Until now. Four women have disappeared in two years. A blue ribbon left near the spot where each was last seen. There are no other clues. And now another young woman has disappeared without a trace. Lilly Martin is trying to outrun a snowstorm when her car skids on the icy road and strikes a man as he emerges from the woods on foot. Lilly recognizes the injured man as Ben Tierney, whom she met the summer before. They've no choice but to wait out the storm in the cabin, but as the hours of their confinement mount, Lilly begins to wonder if the greatest danger to her safety isn't the blizzard outside, but the mysterious man right beside her.
