This is a gripping and touching WWII saga which vividly captures the heartbreak and courage of those battling to survive in Blitz-torn London. When Rose Brown's husband is killed in action at Dunkirk in 1940, she feels as though she's lost a part of herself. Rose can't imagine the future without Ray, but she's certain he would have wanted her to pick herself up and start again. She decides to do something to help the war effort, and soon begins life as a postwoman. And when she courageously rescues a young boy from a bombed-out house and takes him back to her family in West London, she finds a new sense of purpose. Traumatised from losing his mother and being trapped in the ruins alone, seven-year-old Alfie is also rebellious and withdrawn. However, he touches the hearts of the family, who see through his sullen, badtempered front, and with kindness, patience and special insight from Rose, they eventually win his trust. But then a handsome stranger, Johnny Beech, turns up on the doorstep, looking for his son, and everything changes...
