On the highest rock of a tiny island at the edge of the world stands a lighthouse. From dusk to dawn, its light beams out to sea, guiding the ships on their way. The seasons pass and the waves rise and fall. Outside, the wind blows; inside, the lighthouse keeper writes, and the rhythms of his life unfold. But change is on the horizon. A beautiful picture book about hope, change and the passing of time. Winner of the Caldecott Medal 2019.
