As darkness falls and we are snug in our warm beds, a whole other world appears as the lights glow. Whether we look to the skies for faraway planets or closer to home at the owls searching for their prey, there are lights everywhere in the night. The lights can be found all around our world and beyond, in the stars, moon jellyfish, glow-in-the-dark street lights, and even lights from luminous mosses blanketing the forest floor. Dividing the content by where the lights can be found, Sjöberg offers information about each kind of light in tidy paragraphs fittingly set against black pages. Some categories will be familiar, like bioluminescent sea creatures, while others are a bit more fanciful, such as St. Elmo's Fire and ball lightning. The invitingly open layouts are perfect for browsers, and though there aren't source notes, the thoughtful critical thinking questions about the future of manufactured and natural light will get kids thinking. Plus, any book that makes the dark less scary and more wondrous is a plus. Beautiful and enlightening.

Gr 1-5 The night sky may not always be visible due to city lights, but the moon, the stars, and the Milky Way can be seen in areas where there is little human interference. Each page discusses objects in the night sky, plants, animals, ocean creatures, and mysterious lights. Animal eyes appear to glow due to the reflective lenses in their eyes. Animals living deep in the ocean have lots of reasons to provide their own light. Even plants and bacteria have luminescent abilities. Some things can't be seen with the naked eye but can be seen using an ultraviolet light. The interior print is very small, and readers will need ample lighting to read the white text. The dark backgrounds contain plenty of room for numerous illustrations painted in glowing, bright colors. The final pages brighten as the night ends and the sun shines to start a new day. VERDICT Use this title as an overview of the topics, but additional sources will be needed for in-depth research. For students seeking science materials about the bizarre and strange, this book will fit the demand. Sandra Welzenbach, Villarreal Elementary School, San Antonio
