That said, from such a perspective, each writer uses his own literary processes as a singular poetics, which marks his writing. Whithin the framework of such a problem, the work of Nourredine Saadi never ceases to question the relationships between History and fiction and to redraw the boundaries between the factual and the fictional. In his latest novel entitled Boulevard de l’abîme, Saadi attempts to reconstruct the history of colonial Ageria through fiction thus giving rise to heterogeneous and singular writing.
