This is a tetralogy composed of novels, which until now had been read separately. The publication of the four fictions in a single volume reveals that it is a single literary project of high conceptual and aesthetic level. A novel in four parts that raises important questions: What is our relationship, intellectual and emotional, with non-humans? And with the screens that surround us? What are the mechanisms of friendship, desire and mourning? Do the politics of memory lead to the extreme right when they eclipse narratives of the future? How are utopia and dystopia related? Why has mass tourism become the energy that moves the world? How can the most ambitious literature and art represent the contradictions of our time? Jorge Carrión tries out some answers to these questions and, above all, hints at many other questions in 700 challenging pages of fierce originality.
