Reyna Grande's The Distance Between Us delivers another definition of a term border illustrated by the Mexican immigrants or later called Chicano in the United States. To construct the definition, Sara Upstone's postcolonial theory is applied for the analysis of the novel. Literally, 'border' is considered a gate as a place to provide an entrance or an opening used for passage. Thus, this novel depicts the mixture of cultures as a result of struggle committed by the main character of the novel through the passage. However, due to the emergence of chaos as the result of the mixing process, the border is not solely interpreted as a geographical territory but considered a postspace as the mixing involves a breach to an area or space.
