Nine weeks after losing her husband, Charlotte escapes to a wooden motor yacht in New Hampshire, where her shipmates are an aging blue-haired widow, an emotional seventeen-year-old, and the ugliest dog in literature. A genuine bond develops among the three women, as their distinct personalities and paths cross and converge against the backdrop of emotional secrets, abuse, and the wages of old age. <br> Off the boat, Charlotte, an archaeologist, joins a local excavation to uncover an ancient graveyard. Here she can indulge her passion for reconstructing the past, even as she tries to bury her own recent history. She comes to realize, however, that the currents of time are as fluid and persistent as the water that drifts beneath her comforting new home.
