In this, his seventh book, the author uses the figure of Mount Farelo, located in the Region of A Ulloa, Lugo, Galicia, to describe the main events and stories that took place in Spain and Galicia throughout history, as well as myths and beliefs rooted in their peoples. Through the superposition of real and fictional characters and the use of said mountain as a witness to the events, the narrative runs smoothly from Prehistory to the present, showing the lessons and legacies left by the different peoples who have passed through both places. It is a document that briefly and concisely reaches us with a cultural richness that we normally do not have the opportunity to access.
