Russia, 1854: the Crimean War grinds on, and as the bitter winter draws near, the battlefield hospitals fill with dying men. In defiance of Florence Nightingale, Rosa Barr – young, headstrong and beautiful – travels to Balaklava, determined to save as many of the wounded as she can.
For Mariella Lingwood, Rosa’s cousin, the war is contained within the pages of her scrapbook, in her London sewing circle, and in the letters she receives from Henry, her fiancé, a celebrated surgeon who has also volunteered to work within the shadow of the guns.
When Henry falls ill and is sent to recuperate in Italy, Mariella impulsively decides she must go to him. But upon their arrival at his lodgings, she and her maid make a heartbreaking discovery: Rosa has disappeared.
Following the trail of her elusive and captivating cousin, Mariella’s epic journey takes her from the domestic restraint of Victorian London to the ravaged landscape of the Crimea and the tragic city of Sebastopol, where she encounters Rosa’s dashing stepbrother, a reckless cavalry officer whose complex past – and future – is inextricably bound up with her own.
As her quest leads her deeper into the dark heart of the conflict, Mariella’s ordered world begins to crumble and she finds she has much to learn about secrecy, faithfulness and love. But, in the thick of a war fought on more fronts than one, she also discovers a strength and passion she never knew she possessed.
