This chapter has a threefold agenda. First, it aims at positioning Taiwanese American writer Shawna Yang Ryan and her literary work in the context of literary Taiwan, illustrating how identity policy, transpacific politics, and national desire intersect. Second, it demonstrates how the February 28, 1947 “impact event”—key to Ryan’s Taiwan-oriented novel Green Island—is charged with perceptual patterns that share at least three common features: a national trauma, a forced collective amnesia and, a history of betrayal. Third, it shows how Green Island employs family history to reanimate and interact with these cultural patterns by embracing and reconfiguring the traumatic experiences of the generation of witnesses/victims from a transgenerational and transnational perspective. Her ideology-oriented narrative not only formulates ethical concerns and builds a future-oriented historical consciousness, but it also creates a transpacific space from which the trans/formation of Taiwanese American identity can be negotiated against the background of trans/national history.
