The cat's out of the bag… Gregorio Andromedus has finally gone too far, and Calendula Isadora - Callie to her friends - has revealed his soul-stealing crimes to witch kind. But with her mother in peril, and her baby daughter exhibiting strange powers, Callie can’t wait around for her elders to bring him to justice. It’s up to her to take down her mentor-turned-nemesis, using a strategy no witch in her community has ever employed before: with the help of her human friends.

With journeys through cat portals and into spiritual planes, this final volume of the Nightcraft Quartet reveals not only the fate of witchkind, but shows Callie who she truly is. Sometimes, even a witch scientist has to trust her gut.

What fate will the cards reveal?
