Nan Powell is a free-spirited, sixty-five-year-old widow who's not above skinny-dipping in her neighbors' pools when they're away and who dearly loves her Nantucket home. But when she discovers that the money she thought would last forever is dwindling, she realizes she must make drastic changes to save her beloved house. So Nan takes out an ad: Rooms to rent for the summer in a beautiful old Nantucket home with water views and direct access to the beach.  Slowly people start moving in to the house, filling it with noise, laughter, and with tears. As the house comes alive again, Nan finds her family and friends expanding. Her son comes home for the summer, and then an unexpected visitor turns all their lives upside down.
