Charlie Bone awakes one morning to find the city covered with snow & all the animals gone. Where have they gone
- & why? Blessed the dog tells Billy there was a terrible shuddering of the earth & immediately after he saw a witch with two shadows crossing the hall in Bloor's Academy. Could the discovery of an ancient mirror & the movement of the shadow in the Red King's portrait have something to do with it? Then a strange girl appears outside Charlie's house. She tells him he must follow her to find the animals. Can he trust her & will she perhaps lead him to find someone he lost long before the animals? This is the spell-binding final book in the best-selling series.
