This research analyzes Happy Families (2009) by the Mexican writer Carlos Fuentes (1928-2012), prioritizing the micropolitical perspective of circulating affections. The book consists of sixteen stories, which narrate events in different families, interspersed with an equal number of choirs, all independent of each other. We find no repeating characters, nor an outcome where everything finally articulates and gains a conclusion. There are no chapters or parts either. Family stories are narrated in a traditional way - beginning, middle and end - while choirs are shorter texts and narrated freely. The largest of them takes six pages and the shortest, just one line. From a literary point of view, this dissertation will seek to reflect on the relationships at stake in the intimate and family environment as well as in the community space of choirs, prioritizing the micropolitical perspective of circulating affections. The grammar of affections, as well as their materialization in the distribution of bodies in the social space, became opportune for reflection on the zones of contact among different bodies: individual and collective. Furthermore, it examines the relevance of violence, fear and resentment in the affective processes found in the book, as well as the role of the choirs as a tragic and, at the same time, as a strange and distant element. Knowing that Fuentes is a writer marked by the literary boom of the 1960s and 1970s, it reviews the main characteristics and critical arguments about the period. Because it is a work of his final and less prestigious phase, I observe how the bet of the authors of the boom in the recreation of a community seems no longer possible for Carlos Fuentes.
