Teachers often look for books featuring individuals who take a stand about an important issue. They'll find plenty to recommend in this picture book biography [3.5 for me] of Mercedes Sosa, a folk singer from Argentina who chose to lift up her voice in support of change as well as in honor of individuals who worked hard for a living but often received meagre pay for their labor. The unique illustrations, created with Procreate, feature sweeping ribbons of red, pink, violet, and white as well as leafy feathery elements and flowers, all flowing from Sosa as she sang and her audience remained mesmerized by her voice and message. The book describes her formative years as her family struggled to make a living but found ways to enrich her days as well as her rise to fame and some of the challenges she faced with shyness when singing on stage. As she became deeply involved in activism, she paid a price for challenging the status quo, being jailed and forced to leave her homeland for three years. The double-page spread showing her singing her heart out upon her return consists of those same colors seen previously with various symbols also included. An Author's Note, Timeline, a Playlist, and a Glossary of terms enhance the text. Add this one to a classroom collection of musicians as well as one dedicated to individuals who used their voices for change. I was not aware of Mercedes Sosa before reading this biography, but the text brought her to life for me. If I tried hard, I could almost summon her singing even without having heard a single note.
