The old queen and her raggedy witches have fled Witches Borough, and Mup's family has moved into the cold, newly empty castle. But the queen's legacy lingers in the fear and mistrust of her former subjects and in the memories that live in the castle's very walls. While Mup's mam tries to restore balance to a formerly oppressed world, Mup herself tries to settle into her strange new home with her dad, Tipper, and Crow. When an enchanted snow blankets the castle, Mup's family is cut off from the rest of the kingdom, and the painful memories of the old queen's victims begin to take form, thanks to a ghost whose power may be too much for even Mup and Mam to handle. Celine Kiernan weaves a timely and essential truth into the second book of her trilogy: that dismantling oppression means honoring the pains of the past, and perhaps the most potent magic of all is encouraging joy and hope wherever possible.
