Starting from the observation of the rarity of use of the second person in the novel - as a structural element - and its particular distribution nell'extrême contemporain, this study questions the presence of "you" and its quite controversial impact in the current writing practices. Why and how a writer writes the "you"? Far from raising theoretical, historically or aesthetically questions, especially compared to the today itineraries, including the work of Jean-Marie Laclavetine summarizes nodes, this monograph digs in the identity card of the second person, overcoming linguistic and narratological smoothly. Starting from the analysis of several novels that have this shape, it proposes both a model of the novel in the second person as the specific mechanisms of writing this pronoun actives. Offers interpretive keys to the unrest universe of the “Extreme contemporain” of French literature.
