Attack alarm
by Hammond Innes
"Begins in August 1940 at the start of the Blitz. The mass-formation attacks have started, and the call to action stations - "attack alarms" is a daily occurence. This novel offers an account of that long summer when only a handful of fighter planes could prevent a British defeat."
