This paper begins from the assumption that the beginning of the twenty-first century marked the end of an era defined by the “myth of American exceptionalism.” Following Brian T. Edwards and Dilip Parameshwar Gaonkar’s contention that it is the return of the “American trace” that will give rise to a postnational identity, this paper offers a critical reading of Chang Ta-Chun’s Wild Child and Grace Lin’s Dumpling Days . As the analysis of these two young adult novels demonstrates, the figure of the child plays a pivotal role in the ongoing project to envision a “new” American identity, offering opportunities to chart the global exchanges between nations and to question twentieth-century models of global citizenship.
