She hands him a special magnifying glass that used to belong to his grandfather. As you explore the shoreline with Thomas, ordinary grains of sand look like giant boulders, and plain clam shells transform into beautiful mazes. But the real adventure begins when his grandmother gives him a piece of frosted sea glass. That night, Thomas falls asleep and dreams of an old shipyard and a bottle crashing into the waves. Could his little piece of glass have come from that exact bottle? For the rest of the summer, Thomas scours the beach for more ocean treasures. This breathtaking story celebrates the bond between generations and the endless mysteries waiting to be found at the edge of the sea.
