Nature and adventure photographer Paul Zizka offers stunning images and narrative in Spirits in the Sky: Northern Lights Photography. Photos with brief, descriptive captions take center stage. They are accompanied by a few concise sections of text, which provide an overview of what the northern lights (or aurora borealis) are; some of the myths used to explain them; and the stories behind Zizka's work in capturing these breathtaking images. Wildlife, human models, outdoor sports and self-portraits appear among the images, but it is the wildly colorful lights themselves--in the striking landscapes of Canada, Greenland, Norway, Iceland and the Faroe Islands--that make these photos unforgettable. Spectacular scenery and an elusive natural phenomenon combine in special ways in this gorgeous collection of art photography. --Julia Kastner, librarian and blogger at pagesofjulia
