Dedicated to Christa McAuliffe, this inspiring story for young children exemplifies the importance of dedication to an idea, the strength of cooperation and the fruits of pursuing one's vision. A class of schoolchildren create a flag of the Earth set against the vast blackness of space. Despite disheartening reactions to their idea of sharing their flag with all the Earth, the classmates are determined to challenge obstacles and to pursue their dream to display their flag as a symbol, not of different nations, but of the Earth; not of what they are, but of what they may become. Full-page illustrations of this picture book artfully complement the simple yet pointed text that repeats the challenge of the question, "Why not try?"
