Sula is a novel by Toni Morrison about two friends, Nel and Sula, whose relationship examines the confusing mysteries of human emotions. The novel addresses ideas of good and evil and how the two, at times, seem to resemble one another. Morrison uses the theoretical ideas of Jacques Derrida, Edward Said, and Michel Foucault to question the hierarchy of binaries and apply this to race relations in America.
