France, 1921—Tom, a young American orphaned in World War I, is helping comfort the grieving families who travel through Verdun, seeking answers about their loved ones. But nothing in his past—not his rough Chicago childhood nor his experiences driving ambulances across French battlefields—can prepare Tom for the arrival of Sarah Hagen.
From the moment he meets her, a disarmingly magnetic woman looking for news of her missing husband, he knows he will help her in any way he can—even if that means crossing an unforgivable line. As their affair takes them across a fractured Europe careening toward World War 2, Tom and Sarah learn how love can be both a cure for—and a distraction from—the realities of a world turned upside down. But they can only hide from the truth for so long.
When news of an amnesiac soldier in Bologna reaches Tom in Paris, he sets off as a journalist to uncover the story, only to find Sarah at the soldier’s bedside, hopeful as ever. Both are surprised to encounter an Austrian journalist named Paul with his own interest in the amnesiac. As they confront the past, Tom’s actions come back to haunt him, and each is forced to make a choice that will change their lives forever.
