The aim of this article is to explore how Manuel Rojas thinks about, imagines, and fictionalizes the relationship between humans and nature in the context of a society headed towards modernity, using two unpublished texts from the writer's archive: the unfinished novel Astromelia and the short story "El nino y el choroy". In both, Rojas introduces us to characters who, immersed in vital and culturally-diverse contexts, bond effectively with living beings, both human and non-human. Beyond traditional institutions like marriage and family or a political affinity mediated by anarchism, we are talking about characters who make "oddkin" (Haraway) with others-humans, animals, and plants-on the basis of solidarity and reciprocity. In these texts, Rojas invites us to think about small, collaborative, and mobile affective communities, in which diverse subjectivities, not necessarily human, are intertwined.
