With the return of the Housekeeper on the cards, Maeve must find out everything she can about the vengeful tarot spirit in order to finally defeat her. Crossing over into a parallel dimension inside the old school building, she explores the history of the Housekeeper - and spends too long in a world and a mind not her own. With the Children of Brigid closing in once more, and Maeve's friend group now fractured across Ireland, can they hope to ultimately save the town - and Maeve - from the grip of a power greater than they ever imagined?
