This book by the world-famous Argentine writer Ernesto Sabato is rightfully considered the best Argentine novel of the twentieth century and a magnificent example of the so-called “magical realism”, which, together with Sabato, was started by Cortazar, Borges, Amado, Marquez, Allende. The heroes of the novel stand on the verge between life and death, between reality and fantasy. “There is a type of artistic creativity through which the author tries to get rid of an obsession that he himself does not fully understand. For better or for worse, this is the only way I can write.”
