An homage to light.This sparklingly illustrated picture book consists of spare, poetic verse exploring the properties of light; however, it's often too impenetrable for easy understanding ("light laughs in code, / signals in signs…"). Luckily, the book concludes with two pages of scientific context for some of the more cryptic phrases. For instance, Layton explains that the statement "Light tells the space between stars. / It echoes off planets and moons" means that we can see planets and moons-which do not generate their own light-in the night sky because light reflects off them from stars. While the idea of using poetry to celebrate light is an intriguing one, the abstruse verse and in-depth scientific explanations seem geared toward an older audience than the illustrations. The images are the stars of the show, making rich use of color to convey the idea of a shimmering universe. They offer some grounding to the esoteric narrative and present their own secondary storyline in which brown-skinned children (including one wheelchair user) observe light all around them as they shine flashlights at each other, cower from lightning during a storm, and gleefully capture fireflies.
