In 1944, Maren Larsen is determined to do her part to help the war effort. As a cadet nurse at Walter Reed Medical Center, she’s swept off her feet by Dr. Oliver Demarest, whose family spends summers in an insular community on the rocky coast of Maine. In 1970, as the nation grapples with the ongoing conflict in Vietnam, Oliver and Maren are grappling with their fiercely independent 17-year-old daughter, Annie, who has fallen for a young man they don’t approve of. Before the summer is over, a terrible tragedy will strike the Demarests --- and in the aftermath, Annie vows never to return to Haven Point. In 2008, Annie’s daughter, Skye, has arrived in Maine to help scatter her mother’s ashes. Maren knows that Annie never told Skye the whole truth about what happened during that fateful summer.
