"A Fifth Avenue address, parties at the Plaza, two healthy sons, and the ideal husband: what looks like a perfect life for Katharina Edgeworth is anything but. It's 1954, and the post-war American dream has become a nightmare. A born and bred New Yorker, Katharina is the daughter of immigrants, Ivy-League-educated, and speaks four languages. As a single girl in 1940s Manhattan, she is a translator at the newly formed United Nations, devoting her days to her work and the promise of world peace-and her nights to cocktails and the promise of a good time. Now the wife of a beloved pediatric surgeon and heir to a shipping fortune, Katharina is trapped in a gilded cage, desperate to escape the constraints of domesticity. So when she is approached by the FBI and asked to join their ranks as an informant, Katharina seizes the opportunity. A man from her past has become a high-level Soviet spy, but no one has been able to infiltrate his circle. Enter Katharina, the perfect woman for the job. Navigating the demands of the FBI and the secrets of the KGB, she becomes a courier, carrying stolen government documents from D.C. to Manhattan. But as those closest to her lose their covers, and their lives, Katharina's secret soon threatens to ruin her." -- provided by publisher.
