This is the Medal winner from 1995,
Walk Two Moons by Sharon Creech, that I finished reading recently. This book chronicles a 13 year old girl's road trip with her grandparents. Along the way she shares her friend's story and her own with her grandparents. The title
Walk Two Moons comes from the saying, "Don't judge a man until you've walked two moons in his moccasins." The book will open up discussions about seeing life from someone else's point of view, even your parents.
