A lonely old lady finds a new purpose in her painting. Not to spoil a picture book, but: as soon as her paintings started to gain social attention, my hackles went up, expecting a "provide value to earn love" narrative; thankfully, this isn't that. At the end of the day, people leave, Emma is still alone - but alone with her fulfilling work and surrounded by the beauty she's created. That's the way to do it. A picture book about art inevitably suits itself, rich with paintings-within-paintings, vibrant and beautiful. (This is the author/illustrator behind Miss Rumphius and, while not as transcendent, has many of the same charms.)
