Within the field of Latin American narco-literature, women have been commonly portrayed as survivors of both narco and poverty environments, while simultaneously being left out of the main narrative and depicted mostly by male authors. This paper aims to analyze affective representation in the novel Perra Brava (2010), written by the Mexican author Orfa Alarcon, emphasizing the acts of violence carried out by the protagonist, which emerge after a process of personal transformation and are motivated by affections that overwhelm her. It is worth shedding light on the predominant affective dimension present in the novel since it points out a new way of representing violence and crimes in narco-literature, which has not been fully studied in the research related to the narco phenomenon so far.
