Hope Jones hates cars - they turn the air brown and make everyone sick. Her friend Selma has asthma, and Hope's bogeys are black, not green like they should be! There's an air pollution problem where Hope lives, and she's decided to do something about it. Writing on her blog and protesting outside her school, Hope has decided to clear the air by taking on the cars. But with adults so busy thinking about their busy lives, can one child really make a difference?
