An ABC of things unseen: from Air to Zero, and Nothing in between. A is for Air B is for Bare C is for Clear There is nothing to see in this A to Z, other than clues to what was once or may soon be there. The 26 alphabetical scenarios are conceptual, mysterious, and meticulous, deliberately hinting at a story that has happened off the page. Readers are encouraged to explore each letter and soak in the wonder and curiosity of the alphabet unseen. Cleverly illustrated by the beloved Ron Barrett of Cloudy with a Chance of Meatballs, this hardcover picture book is less about the letters you see, and more about the story you don't.
