Sent to stay with her estranged grandmother while her parents try to save their crumbling marriage, 11-year-old Bailey feels helpless and cast away. When a self-proclaimed prophet predicts "a stranger from the sea will change everything," Bailey hopes this stranger can solve her problems--little suspecting her own ability to influence the world. Eleven-year-old Bailey believes in miracles. She has to; it will take a miracle to keep her warring parents together. This summer they are at a Marriage Counselling camp, leaving Bailey and her little brother Kevin with their estranged grandmother in the island town of Felicity Bay. There, an eccentric deposed minister makes a prophecy that a stranger from the sea will change everything. When Bailey discovers a mermaid-shaped piece of driftwood, she begins to believe that the mermaid is this stranger from the sea. Then, when a dolphin becomes stranded on the beach, Bailey forgets her own troubles and rouses the reluctant locals into action. Written in light and lyrical free verse, Shari Green's warm and wistful novel brings Bailey face to face with both hard and beautiful truths about growing up and growing into her own ability to shape the world.
