Summary
Otto meets three mysterious sisters in a forbidden forest and becomes entwined in a quest involving a prophecy and a harmonica. Decades later, the same harmonica connects the lives of three children across different times and places—Friedrich in 1930s Germany, Mike in Depression-era Pennsylvania, and Ivy in 1940s California—as each faces their own daunting challenges and they are all pulled together by destiny.
