"In November 1382, the month of the dead, Abbess Hildegard rides out for York from the Abbey of Meaux... Traveling alone, she discovers danger, encountering first a gibbet with five bloodied corpses and then the body of a youth, brutally butchered. Who was the boy, how was he connected to the men hanging from the gibbet, and what do these gruesome deaths mean? Hildegard is determined to uncover the truth, no matter how terrible it may be. When even her childhood home, Castle Hutton, turns out not to be a safe haven from murder, Hildegard realizes she will have to summon all of her courage and wisdom to counter the dark forces that threaten her friends and family as well as her country."--from publisher description.
