With her grandmother dying, and both parents busy, young Rowan Shea is caught taking care of her grandmother's retail store for the summer. Although, unknowingly to the rest of the family, their grandmother was a witch, who had a lot of magic responsibilities Rowan had to take care of, including tarot readings, mixing potions, home cleansing, and angry gang of demons sent to get back a soul they were owed in the summer of '01? That seems dangerously specific.
