A mother's war / Mollie Walton.

North Yorkshire, September 1939. Rosina Calvert-Lazenby, the only surviving member of her family and widowed by forty-four, has lived at Raven Hall all her life. With war approaching, Rosina must be strong for her daughters, five confident young women who are thick as thieves. When the RAF come to stay at Raven Hall, Rosina finds herself intrigued by their charismatic, albeit young, officer. But is there time for love with the war looming and her eldest daughter leaving home? Grace Calvert-Lazenby, twenty-one years old and newly graduated from Oxford, is determined to live a fuller life. Leaving behind her mother and sisters at home, she joins the Women's Royal Naval Service. Trading the safety and familiarity of Raven Hall for exhausting drills, difficult training and conflicting acts of secrecy will not be easy. But Grace knows that everyone has a part to play in the war.
