The butterfly and the violin : a hidden masterpiece novel / Kristy Cambron.

Enhanced descriptions from Syndetics:

Based on the real orchestra composed of prisoners at Auschwitz, The Butterfly and the Violin shows how beauty and hope can penetrate even the darkest corners.

Present day: 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.

1942: A darling of the Austrian aristocracy, talented violinist, and daughter to a high-ranking member of the Third Reich, Adele Von Bron 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 places: the grim concentration camps of Auschwitz and the inner recesses of her own troubled heart.

"Cambron expertly weaves together multiple plotlines, timelines, and perspectives to produce a poignant tale of the power of love and faith in difficult circumstances. Those interested in stories of survival and the Holocaust, such as Eli Wiesel's Night, will want to read." --Library Journal, starred review
