On a moonlit night in 1903, a mysterious young woman flees alone across the Canadian wilderness. Mary Bouton is 19 years old, half mad and widowed – by her own hand. Tearing through the forest, she is desperate, her nerves burning, and she is certain of only one thing – that two red-headed brothers, rifles across their backs, lurch close behind her. She has murdered their brother and their cold lust for vengeance is unswerving.
