Mary Bridgette has always been a homebody, caring for her family and completing her tasks with a cheerful dedicated attitude. When war breaks out in Europe, drawing her countrymen into the fray in 1917 her heart is pulled to do what she can to help. Joining the Salvation Army's efforts to provide care and succor for the doughboys at the front Mary soon answers the call to follow her heart and her cousin Eric to distant shores. Barrister Abrams, a pilot in the burgeoning field of aeronautics, volunteers to fight with the French Air Force before America even enters The Great War, becoming one of the first of Lafayette's Espadrilles who take the fight back to an enemy decimating entrenched soldiers everywhere. No stranger to the perils of flight, he's still taken by surprise when a crash landing leads to an encounter with a bold Salvationist who risks all to help him. As the war rages on, pulling the two apart, Barrister is often reminded of his chance encounter with the unconventional woman. Through mud and blood, doughnuts and doughboys, the cause will pull these two through heartache, turmoil, and a drastic change of heart. Will a war be the catalyst to unite a flyboy and a simple country girl or will they go their own ways when peace reigns once more.
