A stunning picture book that addresses the question: do any of us "own" nature?      When a curious cat asks the question, "Whose moon is that?", a panoply of animals try to stake their claim. The wolf, the owl, and the starry sky all have their reasons, but the moon ultimately answers for herself -- her light is meant to be shared by everyone.      Kim Krans's stunning ink-and-watercolor illustrations beautifully illuminate this simple exploration of our relationship to the world around us and our place in it.
