In two world wars, intelligence and counterintelligence, prejudice, and self-sacrifice collide across two generations

In 1942, Evie Farrow is used to life on Ocracoke Island, where every day is the same--until the German U-boats haunting their waters begin to wreak havoc. And when special agent Sterling Bertrand is washed ashore at Evie's inn, her life is turned upside down. While Sterling's injuries keep him inn-bound for weeks, making him even more anxious about the SS officer he's tracking, he becomes increasingly intrigued by Evie, who seems to be hiding secrets of her own.

Decades earlier, in 1914, Englishman Remington Culbreth arrives at the Ocracoke Inn for the summer, never expecting to fall in love with Louisa Adair, the innkeeper's daughter. But when war breaks out in Europe, their relationship is put in jeopardy and may not survive what lies ahead for them.

As the ripples from the Great War rock Evie and Sterling's lives in World War II, it seems yesterday's tides may sweep them all into danger again today.
