E. B. Du Bois’s landmark text "The Souls of Black Folk" (1903). Du Bois' double consciousness accounts for the experience of black Americans negotiating a sense of selfhood in the face of discrimination and cultural dislocation. As part of the first generation in her family to be born in the United States, Owusu extends Du Bois’s concept to speak to the crisis of heritage and assimilation for African expatriates and their US-born children." Owusu has stated that “instead of ‘Africanizing’ Western stories, I’m interested in reclaiming African history rendering them into what is happening in the present day.”
