Grandpa Jim can only see a small square of blue sky from his hospital window so Cora decides there's only one thing for it – she will bring him some sea to go with it! First, she brings him a hat full of sea. Then she brings him a hat full of countryside. She even brings him the moon, the black velvet night and the shimmering, glimmering stars. She empties them all out onto the hospital bed for her beloved Grandpa Jim to share. Can Cora bring the hospital ward to magical life until her grandpa is ready to go outside and play with her once more? A heart-warming story about one very special hat. Or should that be one very special girl?
