The article contains an analysis of Boris and Gleb novel written by a contemporary Russian writer Y. Buida. The analysis is realized in reference to certain postmodern tendencies in literature. The author emphasizes mainly the dialogic character of postmodernism and depicts particular features of the movement in post-Soviet culture. Specifically, the dialogic character of the novel is realized through multilayer interferences of culture codes which suit the idea of chaosmic reality by Deleuze and Guatarri. Correspondingly, the dialogue is also displayed by the eclecticism of genders and styles.
