Gilles de Rais has control over every aspect of his life: the servants he employs, the village he lords over, the carefully crafted visage he shows to the world. He dictates where his subjects live, what they eat, if they live or die. He has ultimate power and wields it with a flourish to conceal the dark desires that lurk behind his smile and the despair within his castle in Machecoul. When a wizard tasked with raising a demon loses control of the beast, Gilles's tight grasp on his world begins to slip. His cook plans to flee, taking her son away from the dangers of the castle. His guard wants to claim Gilles's lifestyle as his own. His wizard frantically searches for a way to survive both his lord and the demon he has called into the world. And the villagers - like Jeanetta and her family -move through life in Machecoul too consumed with the task of surviving day to day, and oblivious to the turmoil building within the castle that is threatening to break out and consume them all.
