The volume analyzes more than 150 places that, for some of the greatest literary authors, have represented a 'home': from the modest apartment or rural house of difficult beginnings, to the isolated but complicit dwelling of gradual inspiration, to the imposing mansion, emblem of success finally achieved. A journey that intersects biographies, history, geography, urban planning, architecture and, of course, literature, aided by the use of QR codes: the reader will be able to discover stories, photos and descriptions of those places, as well as access them immediately, visually, with the use of a smartphone or augmented reality viewer (the volume shows not only the 'houses' but also those that are now visitable 'house-museums,' those where one can even stay and those that, to be really lucky, can even be purchased).
