Attending to Latinx South American writing generates a more expansive understanding of how violence and migration shape Latinx literary history and narrative forms. This chapter elucidates the theoretical salience of el Hueco through its multiple significations as gap, hole, hollow, space of detention, liminal status, and form of undocumented migration. Likewise, the chapter demonstrates how the term desaparecido illuminates the emotional holes and the gaps in kinship structures left by those who are disappeared by state terror practices and immigration policies. Using texts by Karla Cornejo Villavicencio, Romina Garber, Juan Martinez, Carolina de Robertis, Ingrid Rojas Contreras, Daniel Alarcón, and Cristina Henríquez, the chapter demonstrates how prose narrative draws linkages between various kinds of state-perpetrated violence in the Américas. The chapter analyzes genres – from creative nonfiction to speculative fiction – and narrative strategies – from temporality and spectrality to focalization and characterization – to illuminate how Latinx South American fiction activates narrative as a form of reappearance and as a means of imagining different Latinx futurities.
