A seaside holiday brings Bernard, Kathleen, Mavis and Francis face to face with a mermaid held captive by a travelling circus, and their daring rescue earns them a journey beneath the waves. There they are swept into a water-war between the merpeople and the sinister Under Folk, and meet the Book People, characters who have stepped out of stories.
Late, inventive Nesbit, full of her trademark humour, for readers who love Five Children and It. Download the free EPUB.
