A Caldecott Honor winner!   Micha Archer's gorgeous, detailed collages give readers a fresh outlook on the splendors of nature. Cover may vary.   When two curious kids embark on a "wonder walk," they let their imaginations soar as they look at the world in a whole new light. They have thought-provoking questions for everything they see: Is the sun the world's light bulb? Is dirt the world's skin? Are rivers the earth's veins? Is the wind the world breathing? I wonder . . . Young readers will wonder too, as they ponder these gorgeous pages and make all kinds of new connections. What a wonderful world indeed!
