Query: The Blind Assassin

Margaret Atwood's 'The Blind Assasin' tells the story of Iris Chase Griffin and her prematurely dead sister, laura. The book alternates between the narrative of the aging Iris, which reflects on her past and her sister's, and a novel attributed to her sister, also entitled 'The Blind Assassin'. This novel-within-a-novel tells the story of a secret affair between an upper-class girl and a lower-class man. The identity of the man is discovered through Iris' story, yet Atwood keeps you guessing which sister is his lover until the very end. I loved this book, and Atwood's insights into society and humanity are poignant and true-to-life. I would recommend to anyone interested in reading a good story.
