While cleaning out her reclusive grandfather?s house, Joplin discovers pieces of a broken platter in a cookie tin. After having the platter repaired, Joplin wishes that she could both find a friend at school, and befriend the girl pictured in the platter. The next day, Joplin befriends a boy named Barrett, and also notices a girl outside her apartment. A girl who looks remarkably like the girl in the platter?
The girl introduces herself as Sofie, and she has a terrible secret. Cursed to grant wishes for the owner of the platter for all of time, she has been trapped for centuries. Joplin and Barrett vow to help her, but freeing Sofie is more complicated than they could have imagined, and the three friends end up against a sinister foe who could put them all in terrible danger.
