"Facundo" is a socio-political critique and historical account of Argentina during the first half of the 19th century. The book examines the life of the gaucho, Facundo Quiroga, who becomes a powerful and ruthless warlord, illustrating the destructive effects of caudillismo (military dictatorship) on society. The author uses Quiroga's life to delve into broader themes such as the struggle between civilization and barbarism, the need for education, and the dangers of unchecked political power.

In "Heroes and Villains," the reader is plunged into a post-apocalyptic world where society has collapsed into barbarism and decay. The story follows Marianne, a young woman from a sheltered community of scholars, who becomes fascinated by the outside world and is eventually abducted by a group of nomadic savages. As she integrates into their society, she forms a complex relationship with the group's charismatic leader, Jewel. The novel explores themes of civilization versus savagery, the fluidity of roles between heroes and villains, and the nature of power and desire, all set against a backdrop of a dystopian landscape that challenges the characters' understanding of humanity and morality.
