Through the trees in St James's Park she spotted the white facades of the Whitehall offices, and her stomach contracted. But it wasn’t nerves. Fortitude, yes, and a kind of hell-bent willingness. An understanding of the importance of her work; to do something, however small, to help. A privilege.

1941: A world away from idyllic childhood summers spent in Devon, Cassie Marsh steps through the sandbagged entrance to the War Room, determined to do her part for the war effort.

The air crackling with tension, the urgency of whispered conversations, the weight of secrets – nothing in her quiet upbringing has prepared her for this. Here, women like her are expected to work tirelessly, remain composed, even as their homes – and lives – are devastated by the Blitz.

But Cassie’s heart is already divided between love and duty. She dreams of rich summers at Greenaways from a lifetime ago, before her world was torn apart. She dreams of one person… the one she cannot – but must – forget.

And as her family begs her to return to safety, to the soothing, reassuring walls of the country house, Cassie must decide where her heart really lies. In times of war, can you ever afford to question your loyalty?

A evocative and beautifully written wartime story of love, duty and courage.
