Eight years ago, brothers Robert and William Hatch embarked on this ambitious project: to interview their heroes and write a book about how they have made America a better place. Florence Griffith-Joyner speaks about her belief in God; cellist Yo-Yo Ma discusses raising his own children differently than his traditional Chinese parents raised him. The subjects speak clearly and simply, very aware that they are addressing a young person, and young adults seeking inspiration and new ways to think about difficult questions will probably be the best audience for this precocious book.
