In recent years, the Cup has moved from the edge of the CATALAN POLICY to the city centre, especially after last year achieving ten Members in the Parlament. But what is it? Where does it come from? What do you want? All of this is summed up in four parts. One is the story of a leftist independentism filled with separations and clashes. Two, we report on the municipal soul of the CUP, how it is spread in the territory and how it responds to municipal problems. Three, internal voices: we talk about how different sectors live. Four well-known people in Catalan society describe how they see it from the outside. The book was published in 2012 in Catalan and this translation into Spanish has been published by the editorial Swing this year.
