When Tamsin was born, her grandmother predicted that she would be one of the most Talented witches in their family. Now that she is 17 years old, it seems pretty clear that Tamsin has no Talent and her grandmother must have been mistaken. She is really embarrassed by her lack of Talent and frequently wishes to be more like her older, more beautiful, and extremely Talented sister, Rowena. While working for her family’s bookstore/magic shop, Tamsin is approached by a handsome young professor who would like help locating a family heirloom cuckoo clock. Unfortunately, Tamsin has no idea that locating this clock could upset the balance of good and evil. So, when he mistakenly calls her Rowena [who is fairly well known for her ability to locate lost items], she chooses not to correct him and, instead, tries to use this as an opportunity to prove herself.
