When Clara Winter left her rural Adirondack Mountain town for college, she never looked back. Her mother, Tamar, a fiercely independent but loving woman who raised Clara on her own, all but pushed her out the door, forcing Clara to build a new life for herself, far from her roots, far from her high school boyfriend, far from the life she has always known. Now more than a decade has passed, and Clara, a successful writer, has been summoned home. Tamar has become increasingly forgetful and can no longer live on her own. But just as her mother’s memory is beginning to slip away, Clara’s questions are building. Why was Tamar so insistent that Clara leave home all those years ago? Just what secrets was she hiding? If Clara, too, carries inside her the gene for early-onset Alzheimer’s, what does that mean for her own future? With great tenderness and humanity, Alison McGhee tells the story of a young woman finding her way in life, determined to know her mother—and by extension herself—before it's too late.
