He signs his name as Rosario Girondo, he writes a personal diary - a shy dictionary of his life - and is so consumed by literature, that he decides to transform himself in the anima of his fiction, becoming a character obsessed with deciphering the art of the personal diaries of his favourite writers, deciding to become part of a secret society of conspirators against the enemies of literature. From that moment, Rosario Girondo will write his diary as if the fate of literature depended on it. A mixture of diary and novel, of emotional journey and auto-fiction of essay and literary tapestry. El mal de Montano proposes how we may take the fight to the enemies of the well-read, as if literature were our only true chance of salvation.
