Misty Inn is up and running, and the Dunlaps have a full house. Willa is thrilled that Kate, her best friend from Chicago, is going to come to Chincoteague for a visit. But it's been a whole year since they've seen each other, and Willa soon realizes their friendship is not as easy as it had once been. Adding to the tension is the fact that a Chincoteague friend, Sarah Starling, is away at camp for the week, not to mention the fact that Ben seems to disappear early in the morning and not show up again until dinner. So Willa is on her own to figure out how to start anew with her oldest friend.
