How does the author use foreshadowing in Black Ice?

In the section titled, June 1989, Lorene represents the "every man" of black society. She is a black woman who immerses herself into white society. In doing so, she is a guinea pig for the black community as she delves into the world of educated, white people. This foreshadows that the reader will see her turmoil as a black woman in a white society. Lorene will either get swallowed up whole into white society or she will thrive and become successful.
