Lessons from Oz by Julienne La Fleur
Lessons from Oz recaptures the magic of the film The Wizard of Oz, while pondering life and illuminating over 35 lessons that we, as grown-ups, tend to forget. Some are whimsical, some are serious, and like Everything I Needed to Know I Learned in Kindergarten, this book will reconnect the reader to the important things in life.
