In a desperate attempt to bring back her lost friend, Savannah, Nancy and the Outcasts accidentally summon her long-lost aunt, Aurora. What starts as a mistake quickly spirals into a dangerous situation. At first, Aurora seems like an invaluable ally, assisting the Outcasts in mastering their magical powers. But beneath her helpful exterior lies a chilling secret—one that drives her to seek vengeance against those she blames, including the descendants of Summer's End and the family of the town's mayor, Charles Talbot.
Facing an insurmountable choice, Nancy finds herself forced to ally with her greatest rival, Emma Talbot. Together, they must engage Aurora in a high-stakes battle of witchcraft, where the price of victory could be everything Nancy holds dear—or the very home she’s fought to protect.
