Potosi is the story of a journey between the south and the north of the world. The protagonist starts her narration in Lima, in Peru, where she settles down and teaches Italian in universities, cultural institutes and high-security prisons. There, she makes the acquaintance of the MRTA and Sendero Luminoso guerrillas, lives fascinating and painful experiences, discovers Patagonia, the Caribbean Sea, Machu Pichu and the Amazon Forest. She gets lost in the Andes, among the children playing in the streets, crosses the Atacama desert in Chile, sees the"salt sea" in Uyuni, Bolivia, and eventually decides to return to Europe. She lives in Milan, Barcelona and Moscow, travels to Lisbon and Sarajevo and finally returns to her hometown in Puglia. This book stresses a transition between "before" and "after", which is always fascinating and unique, enchanting and deep, and should be constantly discovered and invented, just like life.
