Astra is the next Star Darling to go on a mission to Wishworld where she meets a young girl named Emma and figures out that Emma's wish is to make her father proud of her. The problem is that Astra's plan to make Emma's wish come true is ill conceived. Emma's dad is the coach of the school gymnastics team and Astra mistakenly assumes that Emma wants to make him proud by helping the team win the meet. Astra is so focused on her goal that she doesn't see all the signs that she in on the wrong track. While Emma is certainly talented at gymnastics, she feels forced into competing and does not enjoy it. Instead she is a talented artist who wants her father to be proud of her artistic ability. With time running out, Astra's fellow Star Darlings must come down to help make Emma's wish come true.
