Sylvie de la Roche is the daughter of a destitute former nobleman and his wife living in the slums of Paris circa 1847. Her magnificent singing voice is discovered by the irascible, but equally impoverished, old musician, Maître Beaujeu. Under his guidance and training, she is well-prepared when an opportunity comes for her to sing with the great tenor, Lablanche. Overnight, aristocrat patrons are all at her feet – in particular a very intriguing young nobleman and his lady companion. On the eve of her greatest triumph, though, Sylvie loses her wondrous contralto voice. Will it ever be recovered? - Summary by Kelly S. Taylor
