Chester is more than a picture book. It is a story told, and retold, by dueling author-illustrators. Melanie Watt starts out with the story of a mouse in a house. Then Melanie’s cat, Chester, sends the mouse packing and proceeds to cover the pages with rewrites from his red marker, and the gloves are off. Melanie and her mouse won’t take Chester’s antics lying down. And Chester is obviously a creative powerhouse with confidence to spare. Where will this war of the picture-book makers lead?
