Turn is a member of the ancient Crow tribe, a Psychopomp in training—a guide of souls into the lands beyond death—with a bright future ahead of her, until she witnesses the suspicious loss of a soul between worlds. Accused of losing the soul herself, Turn is exiled to the Shadowlands beyond the Crow's city, lands occupied by the mysterious and secretive Raven tribe, weavers of dark magic and suspected by Turn as playing a role in her exile.

But when Turn is saved from sickness and starvation by a Raven, everything she has always believed to be true is thrown into question. As she struggles to adapt to life among the people she once feared, terrible truths begin to emerge. There is a dark conspiracy behind her exile—a rising power that threatens to destroy everything that the Crows stand for, and even to upset the balance between life and death itself. And Turn may the only one who stands in its way . . .
