1940. As the bombs rain down on London, a close-knit community struggles to survive. Working at the local post office, Bessie Green does her best to keep her customers' spirits up, but when she receives a telegram addressed to her parents, there's nothing she can do to prevent the heartache that lies ahead. Then Bessie hears that eleven-year-old Daisy Mason has been orphaned, and she's sure that taking Daisy into their home is just what her parents need. At first, Daisy won't settle, then her handsome brother Josh comes back on leave and things look up for all of them. But the war brings further challenges before they can dare to dream of a brighter future.
