Manhattan art dealer Sera James watched her world crumble at the altar two years ago, and her heart is still fragile. Her desire for distraction reignites a passion for a mysterious portrait she first saw as a young girl—a painting of a young violinist with piercing blue eyes. In her search for the painting, Sera crosses paths with William Hanover—the grandson of a wealthy California real estate mogul—who may be the key to uncovering the hidden masterpiece. Together Sera and William slowly unravel the story behind the painting's subject: Austrian violinist Adele Von Bron. A darling of the Austrian aristocracy of 1942, talented violinist, and daughter to a high-ranking member of the Third Reich, Adele risks everything when she begins smuggling Jews out of Vienna. In a heartbeat, her life of prosperity and privilege dissolves into a world of starvation and barbed wire. As Sera untangles the secrets behind the painting, she finds beauty in the most unlikely of places: the grim camps of Auschwitz and the inner recesses of her own troubled heart.
