As the Blitz ravages London in 1940, Nancy Sparrow decides to leave the job she loves in a West End dress shop and volunteer for war work. She becomes a porter at Paddington station and is immediately thrust into a chaotic environment where air-raids cause havoc to passengers desperate to get home. Meanwhile Nancy's brothers are facing troubles of their own: Mickey loses his nerve in action at the front line and little Leslie suffers as an evacuee. But it is their mother, Lily, who shocks them all when she announces she is pregnant, and her husband, away fighting, is not the father...An unforgettable saga about the indomitable Sparrow family of Sycamore Road, who refuse to let the war dampen their spirits or dim their hope that one day soon, they'll all be together again.
