Echo begins as a fairy tale with Otto, a boy lost in the woods who meets three strange women telling him of a prophecy concerning a rare harmonica. From there, we hear three different stories of four pre-teen children who all live in different times, places, and circumstances, leaning on music to get them through hard times. The tales take you to Germany, Pennsylvania, and California, with storylines interconnected and centered around the possession of a rare harmonica. The audiobook was magical to listen to. I would recommend this beautiful, historical fairy tale to readers for all ages.
