Water in its many guises and the scientific process that commands the shape it takes—liquid, solid, and gas—are the subjects of this collection of paintings. A first-person narration covers the journey of water on its circular path, as streams, rivers, and oceans evaporate into fog and clouds, only to return to earth as rain: ``I am one thing./I am many things./I am water./This is my dance through our world.'' Of most interest but relegated to the back of the book are endnotes by Candace Christiansen (with Locker, Sky Tree, 1995) explaining scene-by-scene the various phenomena the painter's brush has recorded, e.g., a brilliant scarlet sunset is the result of low-angled sunlight passing through layers of water vapor. Locker's paintings and text are poetic, but both have a languid, slightly static quality to them. Unlike Sky Tree, in which science facts were incorporated into the body of the text, the paintings don't illustrate the text in any true sense, but sit on the page. (Picture book/nonfiction. 4-10)
