Courtney Crumrin: Courtney Crumrin Vol. 6 : The Final Spell (Series #6) (Hardcover)

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!
