Hello Lighthouse by Sophie Blackall (2018)

Had to check out the latest Caldecott Medalist. Wonderful story of a lighthouse keeper, who lives alone until his wife comes and they have a child and he is displaced by an electronic light that does not need to be maintained by a person. Gorgeous, creative illustrations - of the power of the sea, the cut away of the different floors of the lighthouse, how they all lived and worked there and obviously loved it. The inside back cover has the story of how the author became interested in light houses and all the facts she dug up to create this charming book for kids and the rest of us.
