Hayley's life hasn't exactly been a piece of cake, and now there's even more change in store: an adorable new puppy, a possible new school, and a new baking challenge - a wedding cake for her grandmother's big day!

With her friends and family pulling her every which way, it's no wonder Hayley's mixed up in madness!
