Wide Sargasso Sea
While Antoinette encounters a lot of hostility in the novel, none really matches the drubbing she gets from Rochester. The fact that he makes passionate love to her in the beginning only magnifies the hurt he inflicts after he receives the damning letter from Daniel Cosway/Boyd. And did we mention that he locks her up in his attic?
From Antoinette's childhood on, Christophine serves as a source of comfort and some pretty solid relationship advice. Her behavior at times, however, does call into question how pure her intentions really are.
