This essay aims to analyze the ways in which H. G. Wells criticizes the ideology of separate spheres that posited the fundamental difference between the genders. In this novel, Wells wages a discursive battle against the ideology by portraying a revolt of a young woman, Ann Veronica Stanley, against not only her father but also the established gender norms. Many critics criticize that this novel starts with a radical feminist novel but ends with a conservative and traditional happy marriage. This essay, however, claims that Wells critiques the conventional notion of women in the seemingly tame marriage plot as radically as in the daughter’s revolt plot. In the novel, the heroine affirms her sexual desire and confesses her love for a married man, thereby taking the initiative of the romantic relationship. Her behavior was considered shockingly unfeminine in that period. The heroine is also rewarded with a happy marriage with the man after an elopement at the end of the novel. This conclusion is unprecedented in the history of English novel by that time, since the heroines who breached sexual behavioral codes were to be either exiled or dead. By not giving her heroine any penalties for her sexual infringement, Wells started a whole new feminist literary discourse in the New Woman novel.
