Katie's Cupcake Club friends all have other activities besides making cupcakes. Mia and Alexis are on the soccer team and Emma plays the flute. Katie sets out to find her extracurricular niche and soon she's dribbling, passing, and catching in an effort to find the right sport for her. Sure Katie can whip up a great cupcake but can she cook on the field too? When Katie tries out and makes the softball team it's batter up...but instead of swinging away she gets nervous during games. What if she makes a mistake? What if they lose? Is this the kind of batter Katie really wants to be dealing with? Katie starts to figure out that doing what you love always makes the batter sweeter.
