In her 10th novel, Margaret Atwood creates an elderly woman named Iris Griffen, who looks back on her life life of privilege and wealth in Ontario, Canada. Alongside Iriss story, we read a bizarrely futuristic novel about obsession, written by her sister Laura, who seems to have committed suicide in 1945. The two stories are enhanced by newspaper accounts about these two women and their families over half a century, and by a stunningly unexpected ending.
