It’s Katie Brown’s first day at her new school and she’s already feeling miserable. Her best friend Callie has been invited to join the Popular Girls Club and Katie’s been left out in the cold. Is their an Unpopular Girls Club she can join? The only thing that makes Katie feel better is the special cupcake her mum packed for her lunch, just biting into the sweet treat stops her feeling so sad. And even better, the delicious looking cupcake attracts three other girls who are also feeling a bit lost at the new school. And as the girls’ friendship grows they decide to start their very own cupcake club – sharing and making their own special recipes!
