After defining the characteristics of documentary literature, the paper focuses on questioning the boundaries between the fiction and facts in the documentary novels by Daša Drndić. The narrative material that refers to reality and history in her novels is related to the theme of the Holocaust, the suffering of the Jewish people in the Second World War and the constant repetition of the trauma of memory. So the documentary novels of Daša Drndić, besides the theoretical questions of the relationship of fiction and faction, also lay ethical questions of the relation of cultural memory and oblivion. The theme combines five separate novels - Canzone di Guerra (1998), Totenwande (2000), Leica format (2003), Sonnenschein (2007) and April u Berlinu (2009) - which are interpreted in the central part of the paper. Elements of faction in Daša Drndić's novels are referred to autobiographical motives related to her life in exile. The exile experience was especially marked by the novel Canzone di Guerra, but autobiographical discourses also appears in novels such as Leica format and April u Berlinu. Each of the novels is an representative example of an engaging documentary novel, which is related to a certain historical period of starvation, and which is accurately substantiated with sources, writings and archives.
