Welcome to Pandora Antiques! With rarities for every occasion. Nowhere does Mia feel so at home as in her Aunt Harriet's antique shop. She couldn't be happier that she can spend her summer vacation there! But something is wrong in the store. Things disappear as if by magic. Furniture that has just been wiped clean is dusty again in seconds. And there are eerie sounds coming from the attic at night. However, her aunt acts as if this is completely normal. Mia, on the other hand, suspects that Harriet is hiding something from her—and not just the question of who her birth parents are. When Mia comes across a ghost one night, her adventures among the spirit world are just beginning . . .
