This narrative belongs to the tradition of thrillers about secret societies. The author takes a historical episode as a starting point and proceeds to construct a story which builds on those events, creating an atmosphere where mystery and fantasy fuse. With a fast-moving plot, where all loose ends are accounted for, the author uses all the resources of both children’s books and mystery novels to rivet the attention of the adolescent reader. At the same time, the author uses historical references which lend verisimilitude to the story as well as a cinematographic exposition that allows us to immerse ourselves in the world he has created.
