Mia loves all her friends in the Cupcake Club, and things are good at home with her new stepdad and stepbrother and going to her dad's house on the weekends. School is okay too with one exception: Mia is failing Spanish! She can speak it at home with her family, but writing is a different story. And when it's parent-teacher night, Mia has a new dilemma: Who goes to that? Mom and Eddie? Mom and Dad? All of them? Mia soon realizes that sometimes having an extra (or a "baker's dozen") of something can be a very good thing.
