Liliana Heker is a prolific writer, and her works often explore diverse settings. To determine the setting of a particular story or novel, I need to know which piece you are referring to.
For example, are you interested in the setting of:
* The Stolen Child: A story set in Argentina during the "Dirty War"
* The Twilight of the Cockroach: A collection of short stories with various settings
* The Trap: A novel set in a small Argentine town
* The Visit: A short story set in a village in Argentina
Once you provide the title of the work, I can give you a detailed answer about its setting.
