Mattie thought living inside the castle was dangerous, but life outside its walls is proving to be just as treacherous. Caught wandering around the village one night by Liam, Mattie is blackmailed into helping him search for his missing sister - a search she knows can only end in misery. Rejected by the villagers as a thief, and forced to live with a grumpy old man who is determined to prove that there is more to her than meets the eye, Mattie has to navigate the confusing social landscape of Mill-On-Rye and figure out a way to keep Liam as far away from the Castle as possible. Meanwhile the dreams and visions that used to plague her inside the castle have returned, and the truth they hint at could be far more perilous than the undead lurking behind the tall stone walls...
