In a battle of torpedoes, depth charges, and secret codes, nothing is as vulnerable as the human heart. 1940 Austrian refugee Karl Lang has lost everything―his country, his home, and his family. All that is left to him is a burning ambition to see the Nazis defeated. Desperate for work and a way to help the war effort, he finds the one place that will take a refugee like a supply steamer traversing a deadly path past enemy U-boats. Since their first meeting, Millie Stevens has felt an undeniable connection to Karl. As the war rages, she shares his determination to oppose the Nazis and finds work at the British codebreaking center at Bletchley Park. There she uses all her intellect and determination to break German codes and read U-boat transmissions―or risk losing the man she loves. Rolf Denhart will do anything to defend the Fatherland, including long patrols in a cramped U-boat. But rumors from Germany leave him uneasy, forcing a choice between loyalty to his homeland, the safety of his family, and his peace of conscience. In the midst of war, three lives are woven together to create an epic tapestry of love and loss, joy and pain, sacrifice and courage.

In a world of high fashion, some are dressed to kill. Marit is looking forward to spending Fashion Week in Paris with her boyfriend Lars at her side. But when the police take her in for questioning concerning a crime she did not commit, she calls the only person she knows who can Cole Bridger. When Cole gets to Paris, he quickly finds that everything is not as it seems, so he enlists the help of his girlfriend, Isabelle, and his cousin Lars to ensure Marit’s safety. Marit has just been named the prime suspect in the theft of a famous fashion designer’s work, and Cole and Isabelle will have to pull out their CIA training yet again to clear their friend’s name. Threats to Marit’s safety are escalating, and Isabelle needs an excuse to stick close to her friend. But for that kind of proximity, she’ll have to go undercover like never as a runway model. The two couples must uncover the secrets swirling.

The line between enemy and ally can shift in a heartbeat. 1940 After her father is murdered, fifteen-year-old Ingrid Lang flees her home in Austria only to become separated from her siblings and stranded in the Dutch city of Arnhem with a pair of broken legs. Her future would be bleak if not for the kindness of a local doctor and his daughter Anita van der Veen. But before Ingrid can finish her healing and continue her journey to find her brother and sister, the forces of Nazi Germany overrun the Netherlands, leaving her trapped in an enemy occupation. Four years later, Gerrit Hendriks, wanted by the Gestapo for his work with the underground, flees to his grandfather’s home in Arnhem, where he finds Ingrid and the van der Veens deeply ensconced in the local resistance. But suspicion, prejudice, and conflicting beliefs soon leave Ingrid and Gerrit at odds with each other. As Ingrid and Gerrit gather intelligence for the Allies, smuggle airmen and other refugees to safety, and plan acts of defiancé against the Nazis, irritations soften and teamwork blossoms. They soon realize that if they want to have any hope of outsmarting a German intelligence officer with a tie to Ingrid’s past, they’ll have to work together. As Ingrid and Gerrit begin to recognize just how much they mean to each other, they find themselves in the middle of an enormous airborne operation, and the imminent battles have the potential to change everything—for Ingrid, for Gerrit, and for the Netherlands.
