Three sisters, three houses, one wolf. In the town of Junction, Lemke must find and save her sister Sorrow, she can feel it in her bones and she hates it. Their youngest half-sister, Brilliance, is reluctant to get involved until a different sort of magic appears and Sorrow - poor, wretched Sorrow - appears to be at the center of it. Lemke learns that she must face and kill the shadow that the wolf left behind and Brilliance learns that not only is she needed but that she is key to Sorrow’s survival; it is her and her alone that is the daughter of the wicked wolf. Brilliance and Lemke must close the divide between them to discover what is really killing Sorrow before Lemke’s knife cuts too deep.
