Dolly Dancer is not like other kids on Sulu Island. Actually, she is allergic to them. She is confined to the valley, a place surrounded by an invisible shield that her friends call the wall. It's the only place they can see her.
Still, Dolly is happy. There are "talkies," which are better than cell phones. And she has real conversations with the sea creatures.
When Tyler and Toni Longo move to the island everything changes, and for the first time Dolly has playmates.
But it's the Sea Whiffet that changes her life forever!
