They say that swimming with dolphins is the number one thing to do before you die. For 12-year-old Michael, it very nearly is. A secret boat trip has gone tragically wrong, and now he lies unconscious in hospital. But when Michael finally wakes up, he seems different. His step-sister Bibi is soon convinced that he is not who he appears to be. Meanwhile, in the ocean beyond Bermuda’s reefs, a group of bottlenose dolphins are astonished to discover a stranger in their midst – a boy lost and desperate to return home. Bermuda is a place of mysteries. Some believe its seas are enchanted, and the sun-drenched islands conceal a darker past, haunted with tales of lost ships. Now Bibi and Michael are finding themselves in the most extraordinary tale of all.
