Cora, an orphan newly arrived from Jamaica, has never felt cold like this. In the depths of winter, everyone in her community huddles together in their homes to keep warm. So when she sees a shadow slipping through the trees, Cora thinks her eyes are deceiving her.

Until she creeps out into the moonlight and finds the tracks in the snow. Agnes is in hiding. On the run from her former life, she has learned what it takes to survive alone in the wilderness.

But she can afford no mistakes. When she first spies the young woman in the woods, she is afraid. Yet Cora is fearless, and their paths are destined to cross.
