Elise, an artist grieving the loss of her son and a fracturing marriage, is in North Norfolk to restore Marsh House to its former glory, its walls adorned with the fading murals and paintings of its long-ago owner, Lilias Carter-Brown. Elise makes an immediate connection to the house, to Sam—a carpenter and a comfort—and to history itself when an old photograph draws Elise into Lilias’s heartbreaking past.

In 1939, with war threatening, Lilias and her sister turn Marsh House into a sanctuary for London evacuees—a young boy and his mother. But it’s the boy’s father, Harry, an enlistee soon to report for duty, with whom Lilias forms an unexpected and intimate bond. When Harry suddenly vanishes without a trace, it changes the course of Lilias’s life forever.

Now, as Elise and Sam work to solve the mystery of the disappearance, the restoration of Marsh House is bringing Elise back to life as well—to love again, to put her and Lilias’s pasts to rest, and to finally move on.
