Bryony and Hannah are sisters, but they couldn't be more different, and war has brought even more of a rift between them. Hannah is young and headstrong. No one will stop her from doing what she wants, and she wants to stay in Jersey. But Bryony is happiest amongst her family and loved ones, and at Combe Lodge everyone is pitching in. The family home has filled with evacuees and Bryony has joined the ATA, helping to ferry planes across the country, whatever the risk. When Jersey is occupied by the enemy, Bryony knows she needs to reach out to save her sister. But is she too late?
