The main objective of this article is to analyze how the contemporary Argentine novel reconstructs the 60s and 70s and how these reconstructions circulate and dialogue with other texts about the period whose documentary capacity of novels to construct a plausible fictional universe in relation to the events of the past. For this I organize and analyze three literary series based on the discrimination of the narrative voices of each novel and trying to think about the circumstances that legitimize or delegitimize the voices and certain narjrations. At the same time, I try to outline some ideas about the poetics that these narratives construct to talk about that period of Argentine history.
