It is late June and the summer of 1940 is about to become the myth that will define a generation. When Len Westbourne, an inexperienced fighter pilot falls in love with Stella Gardam, a radar operator with a far more worldly attitude, they are all too aware that their time may be short as the War becomes an epic struggle between the Luftwaffe and the RAF - The Battle of Britain. Told in intimate, alternate chapters from the perspectives of Len and Stella, That Summer matures into a breathtaking novel: a classic love story vividly evoking life during wartime.
