Five years ago, Lane Kramer moved to Starry Point, North Carolina, certain the quaint island village was the place to start anew. Now the owner of a charming seaside inn, she's set aside her dreams of being a novelist and of finding love again. When English professor Michael Forrester appears on Lane's doorstep in the middle of a storm, he claims he's only seeking a quiet place to write his book. Yet he seems eerily familiar with the island, leaving Lane wondering if he is quite what he appears.

Meanwhile, Mary Quinn has become a common sight, appearing each morning on the dunes behind the inn, to stare wistfully out to sea. Lane is surprised to find a friendship developing with the older woman, who possesses a unique brand of wisdom, despite her tenuous grip on reality.

As Lane slowly unravels Mary's story and a fragile relationship between Lane and Michael blooms, Lane realizes the three share a common bond. But when a decades-old secret suddenly casts its shadow over them, Lane must choose between protecting her heart and fighting for the life—and the love—she wants.
