And there will be blood again … From his Temple in the ground, the Horned God stirs.
When Lord Kabyl of Blanchefort, a young man troubled by the weight of the world, dares give his heart to a girl from a mysterious ancient household, one that pre-dates the League itself, he comes to know the shadows of the past that hover over her.
