It's pool day in the city and everyone is welcome.

Lucy Ruth Cummins is an author, illustrator, and art director of children’s books. She was happily paired with Jean Reidy for both Truman, which was named a New York Times Best Children’s Book of 2019, and Sylvie. She is also the author-illustrator of Stumpkin, Vampenguin, Dalmartian: A Mars Rover’s Story, Our Pool, and A Hungry Lion, or A Dwindling Assortment of Animals. Lucy has swum in creeks, streams, gorges, rivers, swimming holes, pools (above- and in-ground), lakes (both Great and Finger), decorative fountains, and oceans. Her very favorite place to swim, however, is at her community pool in Brooklyn with her sons and her neighbors.
