Neil Davis's decades-long involvement with the aurora extends beyond study and research. He has also been explaining this magnificent phenomenon to diverse audiences, sharing his extensive and continually growing knowledge with his graduate students and his grandchildren, with his fellow scientists through professional publications and with the general public through brief newspaper columns. His years of experience in communicating both the facts and the wonder of the northern lights shows clearly in this book, which amounts to a pocket education in the subject for any reader interested in auroras.
