The brightest stars of summer

The Silver sisters head back to Pruet to help Aunt Sunny plan her wedding, but cake and decorations are not the only items on the girls' agenda this summer. Lily is anxious to show off her swimming skills, while Marigold tries to get over the embarrassment of being cut from one of Hollywood's big blockbuster movies, and Zinnie works diligently on her story in order to gain entrance into an elite writing program. But when Zinnie meets the boy of her dreams, she finds out that he has a crush on her sister.
