Mag lives in a rustic cabin in the Canadian wilds, far from neighbours and further from her past. But when her estranged daughter Beth turns up on the doorstep newly released from prison, the past becomes terrifyingly present. And it has teeth. Beth came to ask Mag a question. But is she prepared for the answer? Can they really settle their scores? And can Mag keep an innocent party from being destroyed in the crossfire? As a blizzard closes in and dangerous words are traded, Mag accepts a challenge from a most unexpected source and lights a fuse that looks set to blow both women sky high.
