Just about everything has gone wrong for Gwen Gilmore over the past year. She's lost her mother, her teaching job, and been dumped by her--albeit not that great--long-term boyfriend. Adrift and out of options, she packs her life into her barely functioning car and makes the lonely drive north, to the only place she can think of going: her family's aging cottage on the Maine coast, Periwinkle, which she's recently inherited.

The cottage and Port Anna, the foggy Maine town of Gwen's childhood, are unchanged in many ways. For Gwen, they are full of the ghosts of her past--boyfriends, forgotten creative dreams, and painful memories of a sister lost too young. Periwinkle is also home to some more literal ghosts: The Misses, friendly spirits who have long watched over the cottage, but who now seem strangely unsettled, slamming doors and moving furniture in the night. And behind its charming façade, Port Anna has not escaped the realities of modern life. Family homes are being razed to make space for garish condos, the cottage, coveted by a relentless local realtor, is about to be condemned, and the unsolved disappearance of a teenage girl has set the town on edge. On the face of it, it's an odd place to try to make a new start.

But there are glimmers of hope everywhere, if only Gwen can open herself up to possibility. Sparks fly with Leandro, an Argentinian artist, as aloof and witty as he is wildly attractive. Old friends and former flames come out of the woodwork, bringing with them new opportunities and chances to laugh again. Even in the face of potential happiness, though, it seems some secrets refuse to stay buried. As the summer crowds return to the city and the locals hunker down for another harsh Maine winter, Gwen will be forced to make choices that will change her life forever.
