"Wide Sargasso Sea" appears to be acting as a prequel to Jane Eyre written by Charlotte Bronte. The story of the novel "Wide Sargasso Sea" revolves around Antoinette Cosway (who was known as Bertha Mason in Bronte's novel "Jane Eyre").Antoinette Cosway happens to be a white Creole heiress. The story describes the time from her youth in the Caribbean to her unhappy married life with Mr. Rochester, and then her relocation to England.She neither belongs to the white Europeans nor the black Jamaicans, but she is caught in an oppressive patriarchal society. The author brings back to life once again Charlotte Bronte's devilish madwoman in the attic.The novel is basically raised on the fundamental themes of racial inequality and the adversities of displacement and the ultimate assimilation. It is one of the greatest classic postcolonial works of fiction.
