The Time of the Hero (original title: "La ciudad y los perros", literally "The City and the Dogs", 1963) is a 1963 novel by Peruvian writer Mario Vargas Llosa, who won the Nobel Prize in 2010.

The Perpetual Orgy: Flaubert and Madame Bovary (Spanish: "La orgía perpetua.
 Flaubert y Madame Bovary" , 1975) is a book-length essay by the Nobel Prize–winning Peruvian novelist Mario Vargas Llosa which examines Flaubert's "Madame Bovary" as the first modern novel.
 The first part of the book has an autobiographical tone; Vargas Llosa then goes on to examine the structure and meaning of "Madame Bovary" as well as its role in the development of the modern novel.
 First published in Spanish in 1975, the book was translated into English in 1986 by Helen Lane.
General elections were held in Peru on 8 April 1990, with a second round of the presidential elections on 10 June.
 The run-off was between favorite, novelist Mario Vargas Llosa leading a coalition of economically liberal parties collectively known as the Democratic Front and political underdog Alberto Fujimori of the populist and more moderate Cambio 90.
 Vargas Llosa won the first round with a fairly low number of the votes, but alienated much of the electorate with a comprehensive privatisation agenda, bolstering the allegedly unelectable Fujimori.
 Fujimori eventually won a landslide victory and would remain president for ten years until he was ousted in 2000.

 The ambitious narrative is built around the stories of Santiago Zavala and Ambrosio respectively; one the son of a minister, the other his chauffeur.
 A random meeting at a dog pound leads to a riveting conversation between the two at a nearby bar known as the Cathedral (hence the title).
 During the encounter Zavala tries to find the truth about his father's role in the murder of a notorious Peruvian underworld figure, shedding light on the workings of a dictatorship along the way.

 Authors who have published with Balcells have dedicated novels to her and included her as characters in her work; she is praised as "one of the most powerful and influential women in Spanish letters."
 She died at the age of 85 in Barcelona on September 20, 2015.
