This chapter draws on Zygmunt Bauman’s notion of “liquid modernity” to analyze three novels: Friction by Eloy Urroz, Lodo (Mud) by Guillermo Fadanelli, and Tomb Song by Julián Herbert. Bauman argues that “social forms” are no longer fixed or stable in contemporary societies but fluid and constantly shifting. This instability inevitably creates a sense of “moral ambiguity” for the characters in these novels, who must navigate the complex social dynamics shaped by globalization in Mexico. As literary postmodernism opens diverse creative possibilities, it also presents authors with ethical dilemmas to the extent of forcing them to confront moral contradictions and uncertainties within their own works.
