The splendor of a Nantucket summer arrives in full bloom. Misty Harbor Inn officially opens its doors, and Gracie Gold, the middle sister, wrestles with an overwhelming decision. How can she even think about staying at the inn full-time when she has a lovely house and grandchildren who need her in Maine? As the sisters try to figure out the day-to-day workings of running an inn, Gracie spends time with the first guests, newlyweds who seem to be looking for different things from their marriage. Can she help the couple find their way? Meanwhile, Caroline questions the wisdom of a decision she made. Will she lose her best friend George forever? And Sam finds a secret room tucked behind a closet. With the help of her daughter Jamie, she finds items, including a cache of old coins, that seem to imply Hannah Montague was a thief who stole a large amount of money before she vanished. But if so, why would she leave it behind? What happened to her? As Gracie and her sisters welcome guests to their charming inn, they are delighted to see how God uses it—and them—to deepen relationships and transform lives.
