"Hayes tells a tender, surreal story about a young child in awe of the sun's warmth... The boy's peculiar charcoal-gray world is brightened by the deliberate use of color, particularly the vibrant yellow of the sun. Hayes's understated and unfussy text provides a sense of reassurance that, though darkness and insecurity may appear in our lives, the light within us never truly disappears."-- "The Horn Book"

"In graphic novelist Hayes' picture-book debut, a boy gains cosmic knowledge... Sun explains that her light 'comes from within'--and that he has an inner light, too. Her touch and the warmth the boy feels lead to an epiphany--'like a little sun inside'--which Hayes depicts as an orange-yellow circle over his heart. It undulates outward in sun-hued rays, powering him back to his loving family. Spare gray line drawings use detail selectively: Hatching textures clouds and earth, and rendering delineates facial features. Humans' skin is the white of the page, like nearly everything in the surrounding space. Crayonlike color is generally reserved for Sun and her selected achievements: plant life, the sunlit sea, a woven rug in sunset colors. Economically told and illustrated yet pulsing with the sun's life-giving energy."-- "Kirkus Reviews"

"This book is a warm hug. I think about this story and smile endlessly."--Kevin "Books Are Magic (Brooklyn, NY)"
