1933, Berlin. Ten-year-old Hanni Foss stands by her father’s side watching the torchlit procession to celebrate Adolf Hitler as Germany’s new leader. As the lights fade, she knows her safe and happy childhood is about to change forever. Practically overnight, the father she adores becomes unrecognisable, lost to his ruthless ambition to oversee an infamous concentration camp… Twelve years later. As the Nazi regime crumbles, Hanni hides on the fringes of Berlin society in the small lodging house she’s been living in since running away from her father’s home. In stolen moments, she develops the photographs she took to record the atrocities in the camp – the empty food bowls and hungry eyes – and vows to get some measure of justice for the innocent people she couldn’t help as a child. But on the day she plans to deliver these damning photographs to the Allies, Hanni comes face to face with her father again. Reiner Foss is now working with the British forces, his past safely hidden behind a new identity, and he makes it clear that he will go to deadly lengths to protect his secret. In that moment Hanni hatches a dangerous plan to bring her father down, but how far she is willing to go for revenge? And at what cost?

‘Smile, nod, and don’t breathe a word of what happens here. Or I’ll put you on the next train to Auschwitz myself.’ Four years later. Hanni Winter shivers in her thin coat as she hurries through the empty Berlin streets to her job. Despite the freezing winter and poverty all around, her cheeks flush when she meets the man she is photographing today, charismatic Tony Miller, the American pilot risking his life to bring food and provisions to the starving people of the city. But her rush of joy turns to ash as she sees the man behind him… It’s been years since Hanni fled her terrible past, but seeing Reiner Foss now brings back harrowing memories of the man they called The Showman, and of the concentration camp he commanded. The last time she tried to expose him, Hanni almost died, can she dare to try again? Or should she seize the chance she sees in Tony’s sparkling eyes to leave the horrors of the war behind? Hanni is no longer the frightened child she was when the Nazis devastated her life beyond repair. She vows to avenge every person who suffered at Reiner’s hands. But does her attraction to Tony leave her vulnerable? Can Hanni protect her loved ones from her past, or will the cost of fighting her demons ultimately prove more than she can pay?
