This is a modern parable about a brother and sister who spend their day playing on the beach by a rock pool. They create their own tiny marine world in a bucket, and with its wildlife, shells, oil, and even a tin can, it is a microcosm of the larger world outside. With a series of stunning watercolors, Michael Foreman makes clear his underlying concern about pollution within the environment, particularly on the seashore. The book's impact derives not only from Foreman's masterly skill as an artist, but also from the strength of his commitment to its theme.
