Grace's only solace is her lover, David Tvedt, a trader who wants to take her away with himif she'd let him.
Yet something else calls to Gracethe loons. They haunt her dreams, lurking in her mind as if part of her deepest primal self. But when Grace is chosen as the new sacrifice, she's afraid. Will she risk everything to help the community that shuns her, or will she choose her own path?
