It is with pleasure that I acquired this book right out to find characters that have both made me travel in the shadow of the wind. But history is short, in the sense that the mystery surrounding this "prisoner of the sky" and David Martin could have been longer maintained, the author could have made us go in turns, dead ends to get to the truth. This is not the case, since from the beginning, we have the right to the story of the history of Fermin. Otherwise I loved to know more about this enigmatic character, the painful past and a sharp tongue, and on this subject, the book is exciting.
