Dabney has lived a safe life on a beautiful island. With her stiff collars and perfectly placed headbands, she has always exuded organization and order. Dabney keeps her life perfectly placed, masking her fear of leaving Nantucket by being the island's biggest fan. Decades ago, she passed up the love of her life to stay on the island. Twenty years later, she has a seemingly happy marriage and a college-aged daughter.
While Dabney goes about making matches among her friends and colleagues, always choosing the perfect mates, her own marriage begins to quietly fall apart. With the arrival of her long-lost soulmate, back from decades abroad, her resolve to live a perfectly manufactured life begins to crumble away.
Dabney spends her summer days carrying on and escaping reality by the pool; believing she can live two lives simultaneously.
But looming within the bright days of a Nantucket summer a deep secret festers. Bad health ignored, perfect plans intact, suddenly Dabney may not have forever to make her mind. She may have less time than she thinks. Nantucket is a summer place with summer people. As the season ends and the crowds depart, the colder seasons settle in. And with the colder seasons comes a cold, hard truth. Dabney must face a daunting reality: that life is imperfect, that love is often uncertain, and that sometimes, we don't have all the time in the world. As time ticks away, what will Dabney choose?
