The Paris Spy's Girl

"As war rages across France, English exile Christine has become the most deadly asset the British Secret Service has in occupied Paris. But when Suzanne, her best friend and the sole agent who knows the details of the top-secret D-Day landings, is betrayed to the Nazis by someone at the heart of their spy network, she is devastated. Going undercover with Charlie - a handsome but elusive American spy with an agenda of his own - is her only chance to catch the traitor in their midst. Pretending to be not only Nazi collaborators but lovers too, they must save Suzanne from almost certain death and prevent the D-Day landing plans from ending up in the wrong hands. But as Christine and Charlie's pretend desire turns to true love, her past - and the real reason she had to leave England forever - puts their whole mission in terrible danger."--
