For generations, the natives of Harrisport have watched wealthy summer families descend on their Cape Cod town, inhabiting the massive cottages along the town's best stretches of beachfront. But when rich Southerner Tucker Moss breaks the heart of local girl Edie Wright in the summer of 1966, an enduring war starts between the two families that lasts for generations....
Edie's youngest child, Lexi, should know better than to fall in love with a Moss, but at eighteen, she falls hard for Tucker's son, Hudson-only to find herself jilted when Hudson breaks off their engagement.
Eleven years later, Lexi returns home after two years away studying architectural photography, just in time for yet another summer on the Cape. When Hudson's younger brother, Cooper, arrives unexpectedly to sell the seaside estate after the death of his father and hires Lexi to photograph it, an unlikely attraction forms, and Lexi finds herself torn once again between passion and family loyalty.
Then renovations at the Moss guest house reveal a forty-six-year-old declaration of love carved into a piece of framing-and a startling truth that will force two women and the men who love them to confront the treacherous waters of their pasts.
