Upbeat and optimistic, the BUCK the CHUCK series stars a lovable but reluctant hero--a woodchuck named Buck--who finds himself at odds with freedom thieves. In each adventure, Buck tackles his challenge with help from his guardian whistle pig, Thor. Each book in the series helps kids understand what it means to live in freedom and just what it is that has made the USA the "shining city upon a hill". BUCK the CHUCK Let Freedom Sing explores freedom of speech.
