It's something else, beyond the storm..." Sapphire and Conor can't forget their adventures in Ingo, the mysterious world beneath the sea. They long to see their Mer friends Faro and Elvira, and swim with the dolphins once more. But a crisis is brewing far below the ocean's surface, where the wisest of the Mer guards the Tide Knot. And soon both Sapphire and Conor will be drawn into Ingo's troubled waters...
