Caitlin and Natalia have been best friends since kindergarten. When Natalia's cousin Emma moved to town, Caitlin missed having her BFF all to herself, but is learning to share the love. All four friends sign up to be on the school carnival planning committee. But when Natalia has to drop out, Caitlin is upset -- she wanted to spend more time with Natalia, not Zoe and Emma!
But Caitlin surprises herself by sticking up for Emma when the eighth grader leading the committee starts teasing her. Now she, Zoe, and Emma are on the mean girl's bad side. Caitlin's normally rock solid confidence is shaken. Emma and Zoe want to quit, but Caitlin is determined not to let a bully ruin their fun!
