1939, London: From McPhail's Passage to Kensington's Grand Palace Hotel, Rose Dunbar is evacuated from her humble home on the Rock of Gibraltar and dropped into a chaotic city of falling bombs, perplexing class rules and bad weather. Despite being 'flagrantly foreign' to the locals, she becomes an efficient go-between for the upper-class ladies helping out with the war effort and her own tribe of noisy displaced families. It is only when she is shifted to the countryside to become secretary to the plain-speaking and sightless Major Inchbold that Rose's dizzying journey to womanhood will become more surreal than ever, as she drinks tea at the vicarage, shields her best friend from abuse and stands up for the lower orders. But Rose's greatest dilemma is yet to come, as she must decide where her home - and her heart - really lies.
