As part of my passion project, I’ve recently finished (and loved) two of Walter Dean Myers’ early picture books: Where Does the Day Go? (illustrated by Leo Carty) and Fly, Jimmy, Fly! (illustrated by Moneta Barnett).
Where Does the Day Go? is delightful. A group of kids are in the park with one of the children’s father, and they have a pretty serious conversation about what happens to the day when it turns into night. Each kid has a theory, but each theory leaves the group with questions. So they take turns telling their theories and trying to answer the questions.
