A third picture book about Katie Morag, a small girl living on an island in western Scotland; here she learns to accept a new baby sister. ""Katie Morag will soon get over it,"" everyone says, but meanwhile she glowers, wets her bed, and even kicks her teddy bear into the sea from the jetty. Sent to Grannie for a cooling-off period, her crossness and the weather blow themselves out together; as the sky clears, she finds treasures on the beach: presents for all the family, including the baby, and, last of all, Ted himself, wreathed in seaweed. This well-worn drama of early childhood is related with as much freshness as a first telling, and given added interest by wonderfully evocative, detailed illustrations. From cluttered interiors crowded with typical island neighbors, a nursing mother cat and entrancing oddments to a landscape populated with seal, otter, and sheep, where you can almost smell the sea and feel the cold rain, the setting enriches the story.
