When eleven-year-old Holly Greenwood knocks on her door, lost and frightened after a forbidden visit to her singing teacher, Ivy's self-imposed exile is shattered. Holly has an extraordinary voice, and wants nothing more than to perform in an upcoming Christmas musical. Holly's father, Daniel, doesn't allow music in their home, refusing to give a good reason why, just as he refuses to talk about Holly's mother. Ivy has no idea how closely she and Daniel are linked by their tragic pasts, yet she's drawn to the warmth she senses beneath his gruff exterior.
