I never asked why my grandmother Mercedes speaks Russian, German, French and Spanish perfectly. Perhaps because I sensed that this why was marked by a delicate history... A history of childhoods without parents. A story of farewells, of reunions, of escapes and persecutions. A story marked by the history of 20th century Europe: the Spanish Civil War, the Second World War, and the Cold War. I never asked why. But now... I need to break that wall. I need to understand which parts of those wars, of those untold stories, still live in me. Join me on this journey through the past to understand where we came from, who we are, and where we are heading.
