One sunny Saturday, Finn visits the beach. The warm sand feels wonderful between her toes, but it would be more fun if she had a friend. Too shy to say hello, Finn watches the kids play nearby, and slowly her eyes droop closed... When Finn awakens she has been transported to a magical underwater world... and she's a mermaid! But who is calling out a greeting from behind that coral? Whose bright eyes are peering at her from the sea grass? Could it be a new friend? Or just another sea creature? Making new friends may not be as hard as you think - if you have a good imagination!
