Paris, 1940: As the German soldiers march down the Champs-Élysées, the Bélanger twins know there is no escape – their lives are about to change forever.

But while Sophie, a third-year medical student, works long days and nights saving casualties of war at the American hospital, and waits anxiously for news of her fiancé from the front line, her recently widowed twin, Adèle, is determined to enjoy her freedom. Nothing – not the bombs, the curfews or the Nazi officers sidling up to her in nightclubs – can stop her from indulging in the temptations of Parisian society as she accompanies their father to glamorous parties.

But rumours are flying through the streets of occupied Paris about their father’s murky business interests, and soon Sophie learns the shocking truth of what’s really happening to their Jewish friends and neighbours.

And then tragedy strikes: their beloved brother is arrested for his involvement in the resistance. Devastated and unable to save him, the family is torn apart – and the girls’ lives are changed forever.

Broken-hearted, the sisters must each find their own way to fight back. As they too are drawn to the resistance, will Sophie learn to break the rules – risking her own life to save as many innocent children as she can? And Adèle faces her toughest challenge yet when she’s recruited as a special agent for the British. Can she overcome her stubborn nature and use her charms to avenge her brother’s death?

One false step and the twins could lose everything they’re fighting for – and each other.

A heartbreaking story based on real-life events, this is a devastating story of lives torn apart by war – and of finding the courage to do what is right, even at the darkest of times. Fans of Kate Quinn, Shari J. Ryan and Siobhan Curham will be captivated by this unforgettable historical novel.
