In her lyrical, cumulative rhyme based on the poetic structure of This is the House That Jack Built, award-winning author Julie Lawson tells the story of a young girl who spends a magical day on the beach, building a sandcastle. While she works, the little girls imagination creates a fairy tale adventure, complete with stately castle walls and whales and mermaids who come to visit. Accompanied by artist Frances Tyrrells exquisite illustrations, this is a beautiful time capsule of childhood.
