On the run from the Coven with her former teacher Calpurnia, Courtney Crumrin is quickly learning just how sinister the witches and warlocks of Hillsborough can be—but she never thought she'd see the day when Uncle Aloysius turned on her as well. It's a lot harder to fight a battle when the only family you care about is against you, and Courtney's only salvation may lie in the Twilight Kingdom—and away from the mortal world. But Aloysius won't give up his niece so easily, even if he has to fight the night creatures to do it!
