What does a problem look like? How about worry or its counterpart, courage? Life is filled with problems, and this tale's main character shares his growing concern over the huge dark blob that looms large and insurmountable. Color scarcely appears in the first pages of metaphoric storms and heavy, dark burdens. But when courage, hope, and opportunity show up, color abounds. When the character's mindset transforms, so does the mood in each illustration. A beautiful lesson cleverly presented.
