The #1 New York Times bestselling author of The Tattooist of Auschwitz and The Wish returns with a masterful new novel that captures the astonishing bravery of ordinary people in extraordinary times.

In 1942, the Nazis come for a Jewish family living in the Montparnasse area of occupied Paris. In the chaos of their arrest, eleven-year-old Josephine runs to the only person she can trust: her piano teacher, Andrée Levallois, a secret French Resistance operative.

Andrée takes her in as a member of the family, spreading their rations and risking everything to keep her safe. But soon the authorities close in, and both Andrée and Josie are caught in a desperate race to stay alive.

Epic in scope and based on real people and historical events, Heather Morris has written a story of breathtaking beauty, at once gripping, heartbreaking, and uplifting.
