Juliet has just moved to a beachside town with her newly separated mother and her moody older sister. When she meets their new neighbor, Emma, the girls form an instant bond. Emma's big family takes Juliet in, and the girls have fun together -- starting with the night they throw bottles with secret messages into the sea.

Then someone writes back to Juliet's message. An email arrives, inviting her to join the Starry Beach Club. All she has to do is make someone else's wish come true.

So Juliet and Emma set off to help as many other people as they can. It's fun! But as Juliet spends more and more time away from home, enjoying her new town and Emma's family more than her own mom and sister, she starts feeling lost. It's been easy to find others to help. But maybe her star would shine a little brighter if she brought it closer to home.
