After Maeve finds a pack of tarot cards while cleaning out a closet during her in-school suspension, she quickly becomes the most sought-after diviner at St. Bernadette’s Catholic school. But when Maeve’s ex–best friend, Lily, draws an unsettling card called The Housekeeper that Maeve has never seen before, the session devolves into a heated argument that ends with Maeve wishing aloud that Lily would disappear. When Lily isn’t at school the next Monday, Maeve learns her ex-friend has vanished without a trace.
