Book excerpt: Children everywhere know that our world needs fixing, but it is the rare author who can put herself in children's shoes, and capture their complicated feelings in words. Susie Morgenstern has a gift for taking serious subjects and making sure they're clever, touching, and never too heavy. In this striking new picture book, she tackles the penetrating question Who is taking care of our world? When a little boy is asked What do you want to do when you grow up? he dreams of improving the world in wonderful ways-but realizes in the end that even the biggest dreams need to start small. Evocative art, hauntingly reminiscent of Maurice Sendak's classic In the Night Kitchen, illuminates the simple but inspiring story.
