I'm jumping waves at the beach with Dad. If they're small I can leap over their frothy peaks. Easy! But further out, when they're big, you have to duck dive under. Maisie is learning about ocean swimming at the beach. The small waves are easy, but how will she know when to dive under the bigger ones? And will she be brave enough to try? Lucky Dad is there to help her. A beautiful picture book from acclaimed author Pip Harry and award-winning illustrator Hilary Jean Tapper.
