Roseanna M. White’s novel, Yesterday’s Tides, has two related story lines taking place in 1914 and 1942 on Ocracoke Island in North Carolina’s Outer Banks.

In 1914, Louisa Adair helps her mother and “Grann” run an inn. She’d like to go to teacher’s college, but there isn’t enough money. Plus, she’s needed at home.

Though Louisa has blue eyes, her skin coloring is darker than most people’s. Her mother will not tell her anything about her deceased father except that he was a good man. A few people are prejudiced against her, thinking she must be of mixed race.

When two college-age cousins, one from Maryland and one from England, come to the inn for the summer, Louisa has no idea how her life will change as a result. Louisa has no plans to fall in love: she keeps a polite reserve with the inn’s male guests. But she and Remington Culbreth, from England, find themselves in each other’s company often. Just after they do fall in love, WWI breaks out and Remington is called to service at home. Will their relationship survive not only the war, but the differences in their families and lifestyles?

In 1942, Evie Farrow now runs the inn with her grandmother. One day while taking some baked goods to the neighbors, a loud explosion is heard in the distant waters. While Evie’s Coast Guard friends prepare to investigate and help, Evie heads home to pray. When a badly burned Englishman washes up near the inn, somehow Evie knows not to report him. He says he is military, but he’s not in uniform. What mutterings she hears as he goes in and out of consciousness alert her to the fact that he is an intelligence officer. But what would an English spy be doing in Ocracoke?

When he wakes up, she learns his name is Sterling Bertrand and he is tracking a German operative. But it will take weeks for his wounds to heal. Meanwhile, he wonders just how far he can trust Evie, who seems to have secrets of her own.

I’ve read many dual timeline novels, and usually there are enough differences between the two timelines to keep from getting confused. I had a little harder time with this one, since both stories took place at an inn in Ocracoke and involved a visiting Englishman. I think I would have had an easier time with reading rather than listening. I didn’t catch some of the names that were the same in both timelines, so I kept getting surprised at the connections. I don’t think that would have happened if I were reading instead of listening.

As it happened, partway through the audiobook I discovered that I did have a Kindle copy! So I went back and forth between reading and listening.

One delight with this book was running into some characters from Roseanna’s previous books. I won’t say which ones, as that might give away parts of the plot. You don’t have to have read those books to understand this one, but it was a fun surprise to see those characters again. Evidently Remington was in an earlier book as well, but, though I remember the story and situation, I don’t remember him.

I’m sorry to say I was not thrilled with the audiobook narrator. Some of her accents seemed a little off to me. Plus she had an odd cadence, her inflection going up when it didn’t need to.

There are so many layers to this novel, and so much more to it than there appears to be at first. I loved the stories, and after finishing the book, I just wanted to sit with the characters a bit more before saying goodbye to them and starting another story.
