What is the theme in No Telephone to Heaven by Michelle Cliff?

Racism is an iomportant theme in the book. Both the action of the narrative (the plot) and the journey of transformation of its central characters (Clare and Charles) are defined and motivated by experiences of racism - specifically, the negative attitudes of whites towards blacks, and the resulting internalization of those attitudes by blacks towards themselves. There is the sense throughout the book that the author is portraying Jamaica, with all its economic and social troubles, as having gotten to that place as a result of systematic and lasting exploitation by whites.
