Paulie Pastrami’s socks don’t match. He is always picked last for sports. And whenever he tries to whistle, it comes out as a breathy “bthtttt.” How could a boy like this ever achieve world peace? First, he starts small, by being kind to animals and reading to trees. Then he apologizes to his sister, helps friends in need and sings often. Finally, he learns the enormous power of...a cupcake. (One grateful recipient kindly reminds readers, “I hear it is as much about the simple act of giving as it is about the cupcakes.”) Paulie Pastrami is a plucky seven-year-old kid armed with a boatload of determination and a whole lot of heart. His mass of wild hair and cartoony wide-eyed exuberance is infectious. Among the many heavy-handed message books about peace, Paulie shines. (Picture book. 3-6)
