Cupcake Diaries

Who's afaraid of middle school? Not Katie Brown. After all, it can't be that different from elementary school. But, boy, was she ever wrong! After her best friend ditches her for a new group of friends called the Popular Girls Club, Katie is left alone and starts to wonder if there's an Unpopular Girls Club she can join. Luckily, Katie finds her way with a great new group of friends and together they form their own club. Four friends plus cupcakes turns out to be the icing on the cake. Written be Coco Simon.
