When night falls, everything is dark. Or is it? The Moon shines with a pale light. A car drives along the street, and when its headlights flash, two bright dots run by. Is it a cat's eyes? Or perhaps a fox's? Stars twinkle in the night sky, and sometimes even the bright belt of the Milky Way is visible. Come on a journey and visit the dark forest, the deep ocean, and the shadows of the city, and discover everything that glows, glitters, and shines in the night! This nonfiction picture book is full of fun facts about all the strange and wonderful sources of light on Earth and in the sky, from the Moon and the stars to glow-in-the-dark insects, luminous underwater creatures, lighthouses, fireworks, and phosphorescence.
