Wide Sargasso Sea is the story of Antoinette Cosway, a Creole heiress who grew up in the West Indies on a decaying plantation. When she comes of age she is married off to an Englishman, and he takes her away from the only place she has known--a house with a garden where "the paths were overgrown and a smell of dead flowers mixed with the fresh living smell. Underneath the tree ferns, tall as forest tree ferns, the light was green. Orchids flourished out of reach or for some reason not to be touched."

The novel is Rhys's answer to Jane Eyre. Charlotte Bronte's book had long haunted her, mostly for the story it did not tell--that of the madwoman in the attic, Rochester's terrible secret. Antoinette is Rhys's imagining of that locked-up woman, who in the end burns up the house and herself. Wide Sargasso Sea follows her voyage into the dark, both from her point of view and Rochester's. It is a voyage charged with soul-destroying lust. "I watched her die many times," observes the new husband. "In my way, not in hers. In sunlight, in shadow, by moonlight, by candlelight. In the long afternoons when the house was empty."
