Once upon a time in a high school English class, we were quizzed on our favorite book. At the time, I was too embarrassed to admit the truth—that the books I loved were children’s books. And I still do. From picture books to young adult, there are stacks of children’s books beside my bed, on my desk, and in my living room. Most of all, I love nonfiction, those stories that tell the truth of our amazing world.
