A WWII historical romance of forbidden love, family torn apart by war, and a city on the edge of annihilation, from New York Times bestselling author Sherrilyn Kenyon, writing as Kinley MacGregor

Saving the city may mean destroying the people they love most.

Paris, 1944. Amandine Lundy has spent the war surviving quietly—until the conflict inside her own family becomes impossible to ignore. One sister risks her life as a leader in the French Resistance. The other has fallen in love with a Nazi officer and believes his promises of a future free from bloodshed.

Caught between them, Amandine has always chosen loyalty over safety. But when her younger sister asks her to help ignite a plan that would leave Paris in ruins, Amandine draws a line she never imagined crossing.

Sebastian Edwards is not the man he appears to be. Posing as a Nazi officer, he is an English spy with a single mission: stop the order to burn Paris at any cost. He has dismantled every attempt so far—until Amandine places herself directly in his path.

She is innocent in ways the war has not yet stripped away. Loving her may be more dangerous than any enemy. Yet her sister is entangled with the very officer Sebastian reports to—and mercy could unravel everything he has fought for.

As Paris stands on the edge of annihilation, Sebastian and Amandine must choose between duty and devotion, resistance and family, survival and sacrifice.

Gripping, emotionally devastating, and rich with historical detail—Across Enemy Lines explores the impossible choices war forces upon families, and the quiet courage it takes to love when everything is burning.

Perfect for those who love: WWII romance with spy intrigue and moral complexity; families divided by war and impossible loyalties; forbidden love against a backdrop of occupation; high stakes and heartbreak.
