While his sister is hospitalized and during her recovery from her injuries, Antoine becomes compelled to find out more about his mother and who she was and how she died since both of her children feel as if they never really knew her and the subject has never been talked about within the family. In the course of his inquiries, he discovers and faces the truth about a mother he loved deeply but lost far too soon.
Antoine is a very complex man who is simultaneously dealing with his love and longing for his ex-wife and their three children-- two of whom are surly and distant teenagers -- and with the sudden urge to finally know more about his mother. He suffers loneliness and self doubt, bored with his career as architect, and morose about his lack of close relationships with his children and his father's family. I found him an interesting character with a lot of depth and sentimentality that led to many moments of self examination and introspection. The other supportive characters were not so well drawn, but did provide the means for Antoine to interact with and to push the narrative along.
