Summer vacation in London turns mysterious and exciting when Mia learns that her aunt's antique shop is actually a ghost placement agency and she gets training in how to cross over into the spirit world. Welcome to Pandora's Antiques, with rarities for every occasion. Nowhere does Mia feel so at home as in her Aunt Harriet's antique shop. How wonderful 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 dusts up again in seconds, and there is an eerie number of clatter 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--just like the question of who her birth parents are.
