“All it takes is / One hand / One smile / A single voice . . .” (n.p.). Adults and children share equally in this summons to create “a little peace” (n.p.). The book’s message, that peace is possible through cooperation and under standing, appears only through the photos, which subtly draw attention to our shared commonalities and prevent the book from becoming didactic. Back matter includes a world map that pinpoints all locations. Thumbnails of photos, credits, locations, and a detailed explanation of each pictured ac tivity help identify how citizens of the world come together to create peace.
