When their ethno-musicologist uncle goes missing, he leaves his twin niece and nephew clues to help find him. Stuck in history, in places and times where music had played important ethnic roles—the kids are hot on their uncle‘s heels to find him and to save music from a bad guy hot on their heels. A jaunt through music history, including jazz, bluegrass, and meeting Mozart. #litsyatoz #scarathlonatoz #LetterJ #scarathlon @Catsandbooks
