Enemy Sighted. Shadows of War, #7

As bombs fall across England, and dogfights tear through the skies, a traitor lays his plans. Evelyn Ainsworth has a problem. The documents left behind by her father hold an ominous secret, one that he wouldn't entrust even to MI6. Torn between duty and loyalty, she's determined to learn the truth. But with an enemy spy getting closer to hunting her down, even England doesn't seem safe anymore. Flight Lieutenant Miles Lacey and his squadron are battling the Luftwaffe every day, but their frustration is mounting.
The RAF is outnumbered four to one on fighters alone, and massive raids of German bombers are intent on destroying every airfield in England. Despite their success in the air, the odds are taking their toll as they struggle to keep pace in the Battle for Britain. An elusive enemy hidden deep within Whitehall, smuggled plans that Berlin wants back at all costs, and a desperate fight for freedom hanging on the wings of a precious few. The fight for survival is just beginning.
