It's 1977 and an air of restlessness has settled on the residents of Cambridge Road in Rochester, New York. When Nina Larkin is given a copy of The Joy of Sex by her newly divorced friend, she can no longer dismiss the nearly non-existent intimacy of her marriage. Just as her oldest child, Clara, is falling in love for the first time, Nina finds herself longing for the forbidden: a midlife awakening. An intoxicating fling with a neighbour brings Nina a freedom she never thought possible-but also risks the reputations of both families and unravels Clara's world, just as she stands on the threshold of adulthood.
 
Years later, Clara, now a successful food stylist in New York City, has never been able to move past the long-ago scandal. Drawn back home by the pull of a family wedding and wrestling with her own demons, she makes a pivotal decision that turns her life upside down. 

Written with Cynthia D'Aprix Sweeney's signature humor and insight, Lake Effect is a wise and probing look at love and desire, mothers and daughters, loss and grief, and what we owe the people we love most.
