This is the story of the budding friendship between the little seagull Emma and the little raven Max. Max feels like many small and large vacationers who are visiting the North Sea for the first time and wonder during low tide: Where is the sea? During an extensive walk on the beach, Emma's grandpa explains to the two of them the interplay of ebb and flow and shares stories about the inhabitants of the tidal flats, such as crabs, lugworms, seals, and oystercatchers. The experiences of Emma and Max are depicted in humorous yet very detailed illustrations. Not only children will love the illustrations with their countless details!.
