The year is 1942, and American secret agent Catherine Thornton has no idea whether she will be dropped behind enemy lines in an inflatable raft launched from a submarine or be flung through the moonlit sky from a low-flying British Halifax. Either way, the young embassy wife and erstwhile journalist knows there’s always the chance she’ll be picked off by German sharpshooters, although nothing in her imagination prepares her for the trial-by-fire to come.
Only she understands why she volunteered for such “unwomanly warfare” and the secret reasons she joined a handful of female American spies destined to risk her gilded life on French soil–yet former Vichy diplomat Henri Leblanc, code name Claude Foret, thinks he knows the answers.
As Catherine’s missions grow more harrowing each day, and she fears she’s fallen in love with a captured fellow agent, the German SS begin to close in on the world of Madame “Colette Durand” and her Résistance network embedded in coastal cities along the French Riviera—an exposure that could threaten the Allied victory itself.
And hanging in the air like a half-opened parachute is the life-or-death question: Who is the betrayer and who will be betrayed in this, their finest hour?
