Light of the Moon - Elizabeth Buchan

I thought loving someone was simple. It isn't. Glorious, yes. Painful, yes. Unforgettable, yes. Simple, no. It took me the war to find out... Evelyn St. John has been parachuted into France to link up with the Resistance and to work undercover. Paul von Hoch's brief, as a member of the German Intelligence, is to track down enemy spies. When Evelyn and Paul meet and fall in love, their feelings for one another are fierce, but can never be uncomplicated. And when the battle lines shift, and patriotism gives way to deeper truths, they will both face the gravest of challenges.
