From bestselling creators of The Girl and the Dinosaur comes a new picture book about the value of imagination and storytelling, and the love between a girl and her grandmother.

Alina lives in a lighthouse by the sea: a home filled with the warmth of Granny's magical stories.

But Alina is worried. Granny's memories and stories are starting to fade away, and she doesn't know how to bring them back. Then, one day, Alina meets a mermaid on the rocks near the lighthouse-and she's swept into a magical adventure deep under the sea. Can the mermaid help her find the stories, and can Alina help to keep the memories shining brightly?

This heartwarming picture book takes readers on a deep and fanciful journey to explore the importance of family, memory, imagination, and storytelling.
