"Northern Lights" is a great addition to any library. The writer does a wonderful job of explaining how the northern lights are generated by the complex interaction of solar wind, the atmosphere, and the Earth's magnetic field. Kids will also enjoy the collection of legends and superstitions about the northern lights that the author has collected. This book is a thoughtful balance of beauty and physics for schoolchildren and would be a valuable resource for science reports.
