Asian American writers have long produced literary works of speculative fiction, the supergenre that employs science fictional, fantastical, or supernatural elements. Stephen Hong Sohn's Asian Ameritopias is the first book-length study to consider how these aesthetically complex and wildly imaginative representations offer writers a way to explore themes of race and identity, as well as alternate futures and other planets. Sohn examines how various novels and stories enable Asian American writers to engage with and reimagine issues of social justice, revisualize the bounds of social collectives, and create new pathways for precarious subjects. Asian Ameritopias assesses speculative fictions that spotlight supernatural horror and fantasy, such as ghosts and magical objects, to excavate racialized histories of oppression. Moving to science fiction, Sohn shows how Asian American cyborgs employ their technological powers to offer protection for socially marginalized groups, including sex workers, the undocumented, the poor, and the injured. He ends by analyzing three novels featuring extraterrestrials who look like Asian Americans in order to address issues of xenophobia and ostracization. The speculative fictions Sohn unpacks in Asian Ameritopias provide a ripe opportunity to reflect on and confront our current, turbulent reality.
