Roa Bastos' life and writing were marked by experience with dictatorial military regimes. In 1947 he was forced into exile in Argentina, and in 1976 he fled Buenos Aires for France in similar political circumstances. Most of Roa Bastos' work was written in exile, but this did not deter him from fiercely tackling Paraguayan social and historical issues in his work. Writing in a Spanish that was at times heavily augmented by Guaraní words (the major Paraguayan indigenous language), Roa Bastos incorporated Paraguayan myths and symbols into a Baroque style known as magical realism. He is considered a late-comer to the Latin American Boom literary movement. Roa Bastos' canon includes the novels "Hijo de hombre" (1960; "Son of Man") and "El fiscal" (1993; "The Prosecutor"), as well as numerous other novels, short stories, poems, and screenplays.
