See the first chapter, "Routes of Desire: Chimamanda Ngozi Adichie" (21-74). Here's the abstract for it:
This chapter examines Chimamanda Adichie’s third novel, Americanah (2013), and argues in its first section that by expanding its scope beyond the notion of the nation, the novel creates a relational world that exists in the gaps between the local and the global. These geographical relations are always closely connected to stories of love and desire which act as the driving forces behind Americanah’s diasporic movements. The second section of this chapter extends discussions of the novel’s transnational routes by examining its textual, textural entanglements via the main linking devices the novel employs, hair and the internet. The third part of this chapter expounds the notion that there lies subversive potential at the heart of Americanah’s love story as both its protagonists return to Nigeria from the years spent abroad elsewhere. Subverting the conventions of a “successful” migration narrative that includes processes of assimilation in the West, while seemingly conforming to the conventional structure of the romantic “happy ending”, the novel displays an innovative way of imagining Africa and its diasporas.
