Thesis Statement: Jamaica Kincaid uses the theme: Love and Family Relationship to capture the conflict that Lucy feels about escaping from her biological mother only to find Mariah as her surrogate mother with whom she shares opposing views.  

Explanation:

In the novel Lucy, by Jamaica Kincaid, a young woman that was born and raised in the Caribbean becomes enveloped in life in the United States. She becomes the employee of an idealistic white woman Mariah that epitomizes white america.

In this novel Lucy must define herself as an individual and accept herself at the same time she must come to terms with her country and upbringing that she had no control over and accept that her relationship with Mariah is that of an employer/employee and nothing more despite their differences in opinion.

It is apparent that Lucy is indeed ignorant of her new surroundings and knows nothing much outside of what she was raised in. At the same time she is eager to set herself free only to find that she is more like her mother than she wanted to be.

She was also unpleasantly aware that she had placed Mariah in the role of surrogate mother when she in fact is nothing but her boss. Lucy is in an internal conflict and in the end must resolve her internal issues before she is completely free.
