"Ken is an enthusiastic swimmer but he lives in the country and the only place to train is in the sea. When his best friend Caro gets her driver’s licence, the two of them join a swimming squad in the city. But while Caro seems to improve, Ken is struggling. The arrival of Ken’s Aunt Maya from Japan changes everything as she tells him the story of the Whale’s child and its significance to his heritage." (from author's website)
