Have you ever dreamed of the vast library that grows under our feet as the roots of the city, preserving the memory of all that exists? Have you thought in the enigmatic nakedness of the human skin, the skin more fragile and vulnerable throughout the animal kingdom? Or the striking similarity between human skin and the role of books? What about the human obsession by dressing the skin of other species? Marta Tafalla fantasy and humor woven with the threads of a story that goes from the dark depths of Germany and the underground city of Barcelona. A novel organic, flexible and dedicated to fine those who can not read.
