The American Wife's Secret: Epic, heartbreaking and unputdownable World War 2 fiction (The Diplomat's Wife Book 3)

Kitty held her husband close to her chest, covering his body with her own. She called for help, but none came. She stared down at the face she loved so well. “Don’t go, my darling. Not now. Not after all we’ve been through…”
1944. Vienna: Now a seasoned American spy, Kitty Larsson knows better than most that fighting the Nazis comes at a price. She’s worked undercover as an agent for the British and now does so for the Americans. She knows that doing what is right comes at the highest price...
When the OSS sends Kitty back to Vienna for an important assignment, she discovers that Edgar has been involved in a deadly mission. But it all goes wrong, and now her worst fears are realized. The Gestapo discovers who she is. They warn her husband’s life is now in her hands. If she doesn’t cooperate, he will die. Kitty’s secrets might be enough to save the man she loves… But what if they are lying…?
Fueled by her desire to do what is right, but also to save the man she loves, Kitty knows that she won’t be able to rest until she finds out what’s really happened to Edgar. Because, somewhere out there, she knows he has to be alive…
As the war rages, Kitty tries to think of a plan. Surely this isn’t where it all ends? She needs to know whether Edgar is safe—to hold him in her arms again!—but, to do that, will Kitty finally have to make the ultimate sacrifice?
