Lost in the Black Forest, Otto meets three mysterious sisters and finds himself entwined in a prophecy, a promise, and a harmonica--and decades later three children, Friedrich in Germany, Mike in Pennsylvania, and Ivy in California find themselves caught up in the same thread of destiny in the darkest days of the twentieth century, struggling to keep their families intact, and tied together by the music of the same harmonica.

Torn from his home and parents in Poland during World War II, a young Jewish boy starving in a concentration camp finds hope in playing Schubert on his harmonica, even when the commandant orders him to play.

Teaching playing the harmonica in three basic stages, this book emphasises actual practice exercises with blues, rock, bluegrass, folk and jazz music.
