This is a lavishly illustrated children's book, written in rhyming verse, that describes what light pollution is, and how it can be prevented. There is an index in the back on specific terms used in the book. Written by Bob Crelin, the inventor of "GlareBuster" lighting fixture, designed to prevent light spill for commercial and residential uses. The illustrator, Amie Ziner, created the pictures using accurate star fields (to the 3rd power of brightness), the first children's book that was technically accurate in terms of the astronomy that was not a textbook.
