In her new novel 'Lake Effect', author Cynthia D'Aprix Sweeney chronicles the ripple effects of a shocking divorce that rocks an entire 1970s community in Rochester, New York. As the marriages of neighbors Finn and Honey, and Nina and Sam, unravel, the adults and their children are forced to reckon with the breakdown of their relationships and the social fabric of their tight-knit neighborhood.
