Hiaasen, Carl. (2005). Flush. New York, NY: Random House. This realistic fiction chapter book tells the story of Noah, whose father was put in jail for trying to expose local water pollution. In typical Hiaasen style, the adult characters are quirky and helpless, and the kids must step up to save the day. Older students will love the humor and be inspired to speak up against injustice. Grades 5-8.
