The book narrates and explains the events that, after World War I, led to what happened during the Interwar period and during World War II, which left such deep scars on humanity. In this book, which is based on the History lessons of Maria Efthymiou and so artistically and lovingly designed and composed by Dimitris Giannakouros, the events, the dates of significant battles, and the Treaties signed are presented in an understandable and vivid manner. What is mainly attempted, and what Maria Efthymiou also strives for through her lessons, is to provide an explanation for what happened, so that we understand that we always have responsibility for our decisions and that our actions have consequences, whether they concern our daily lives or the relations and agreements between states that affect global developments and life on the planet. Because, as we unfortunately realize once again, the danger of a generalized conflict is not far away. "It is a graphic embroidery, a powerful artwork, a feat of creation and dedication, for an aesthetic and intellectual pleasure." (Maria Efthymiou, Professor of History at the University of Athens).
