This book has a glow in the dark cover that immediately intrigues, as do the pages that follow. Perfect example of a young reader science-orientated picture book that is full of simply worded facts and gorgeous illustrations. Covers so many different aspects of light and contains a useful bibliography.

This picture book nonfiction for very young readers. showcases different sources of light. Each source gets a two-page spread featuring color against a dark background, accompanied by 2-3 words describing properties of the light "crystal jellyfish shimmer," "fire warms." Most pages use common names; a few use more complex scientific names. The paintings are striking but printed on flimsier paper with a glossy sheen. A matte finish might have made the color and light work in the art stand out even further. Still, a solid early science picture book with opportunities to talk about color and nature and that introduces rich verbs associated with light. Backmatter includes brief additional facts about light sources, bibliography, websites, and index. The layout of the light sources section is a bit compromised by two sources spilling onto the next page, cramped above the bibliography where they're easily lost.
