A picture-book biography of Sister Rosetta Tharpe, the woman who invented rock and roll — a warm, inspiring tale of a childhood filled with music, community, and a drive to succeed. “Music is the heart of our story” says Momma to young Rosetta, surprising her with her first guitar. Rosetta‘s strums sound like ker-plunks. But with practice and determination, she makes music, fingers hopping “like corn in a kettle,” notes pouring over the church crowd “like summer rain washing the dust off a new day.”
