In 2016, 34-year-old Mari Starwood travels to Martha’s Vineyard with nothing but a name on a piece of paper: Elizabeth Deveraux. Mari isn’t sure what to expect when she finally makes it to the reclusive artist’s stunning waterfront property, but she is shocked to find out that her relationship to the island runs deeper than she ever thought possible. In 1942, the Smith sisters are faced with the impossible task of holding their family farm together during WWII as the U.S. Army arrives on Martha’s Vineyard and their brother ships out to fight on the front lines. In an attempt at normalcy, the girls start a book club that soon grows in both number and influence. But their lives are upended when a mysterious man washes up on the shore, and they find themselves questioning who they can truly trust in these turbulent times.
