This is a book written against the fear. A tool made to provide some answers to the questions raised by the independence of Catalonia. Keys that foster the debate on the country we wish to build together. Keys elaborated from the certainty that the Catalan nation can only endure by means of a sovereign state. Keys written from the respect for truth and factchecked data. Keys delivered by fourteen civic entities from Catalonia to help us imagine how we should set up this free country that, finally, we have decided to achieve.
