What is the author's tone in Shizuko's Daughter by Kyoko Mori?

There is a rebellious tone to the narrative. The traditional role of the woman is very clearly defined in Japan. From the type of clothes she wears and the kind of makeup she applies to her face to the courses she studies if she should decide to go to college, all are dictated to her through a long tradition of social rules. Despite her intelligence, skills, or natural talents, she is expected to marry by a certain age, to give up her profession, and to focus all her efforts on the welfare of her husband and her children. She is also expected to maintain social grace, which often means that she does not express her true feelings.
