In the early days of World War II, the Lang family lost everything. Eighty years later, it’s time to take it back. The Nazis have taken control of Austria, and wealthy widower Leopold Lang faces a difficult decision: join the ranks of the foreign power that has taken over his homeland or flee with his children to safety. Leopold makes his choice—but too late. His family is ripped apart, never to be reunited. But decades later, fate brings together the descendants of this broken dynasty in the place where it all began—Falcon Point. Anna, Cole, and Tess have never met, each relying on fractured pieces of information to understand their Austrian heritage. But when unforeseen opportunities draw these Lang cousins to Falcon Point, they soon discover they are not alone in their quest to claim the coveted property and the fabled treasure hidden within. Unfortunately, another claimant, one with a much darker heritage, is determined to eliminate the Lang family once and for all.

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.
