Background. The article is devoted to the problem of reconstruction of collective memory in Alberto Méndez's novel "The blind sunflowers" (2004). Méndez's book is a part of contemporary Spanish narratives that, since the 1990s, have witnessed the emergence of the so-called "memory boom", a trend in literature and cinema aimed at preserving, restoring and transmitting the memory of the tragic events of Spanish Civil War and Franco repression. The purpose of the research is to reveal the ways and mechanisms of reproduction and elaboration of traumatic collective memory in "The blind sunflowers" by Méndez. Methods. The study is based on the following methods: a historical-cultural approach and "memory studies", which made it possible to determine the place of the Alberto Mendez's novel in the context of the Spanish "literature of memory" beginning 21st century; the narratological and intertextual approaches were used to investigate various techniques of the author's creation of a polyphonic narrative in four stories that make up the book, and which represent different voices of the same past, functioning as symbols of restoring the memory of defeat. Results. The artistic recreation in "The Blind Sunflowers" of the traumatic experience of the events and consequences of the Civil War in Spain was investigated in dichotomies typical of the depicted historical moment: winners-losers, victim-executioner, death-life, memory-oblivion and voice-silence. The analysis of this traumatic context in the novel proved that writing (the voice of memory) functions as one of the main ways of preserving the experience of erased generations, restoring life after physical death, and as a guarantee of resistance to oblivion. Conclusion. The reconstruction of the memory of the Civil War in Spain and its consequences during the period of Francoism as one of the leading trends in modern Spanish literature demonstrates the still openness of collective trauma and, accordingly, the need to find ways to overcome it. In view of this, the approach proposed by Méndez in "The Blind Sunflowers" to restore and transmit memory through a collective discourse of defeat becomes a significant step towards healing the unhealed wounds of a society traumatized by war and a dictatorial regime, as it emphasizes not only the importance of the grieving process in overcoming tragedies, but also attests to the creation of literature as a space of memory, in which the past is reproduced as a voice that breaks the silence and overcomes oblivion, not allowing to turn the page and close the past.
