The name of Julio Cortázar resonates around the world for its literary quality and for his deep commitment to the human being. Considered one of the most important authors of the 20th century, his life was as controversial and exciting as his work. He wrote, traveled through different countries and spent long periods in them, leaving an indelible mark as a social prophet, especially in Latin American lands. In all that time Cortázar never forgot his destiny and fought for his ideals, be they artistic, political or metaphysical, and always under the umbrella of literature, his old childhood friend who accompanied him to death. But behind this charismatic and cosmopolitan author, an unusual individual was hidden: a person of extraordinary sensitivity who lived marked by family trauma and by a conflictive relationship with his own country, Argentina. Cortázar was a man of great loves and excellent friends, also of dark secrets. Based on recent documentary findings, Miguel Dalmau builds a rigorous, vibrant and daring biography, a portrait that moves away from the usual academic patterns to show us the most intimate and unknown side of an exceptional artist.
