The merit of this book is to make the link between the sky and the shadow play of the angel revealing a bit more life to one of the most beloved characters from the shadow of the wind. Some aspects of the prisoner of heaven are too close to Alexandre Dumas and the Count of Montecristo giving a "called" appearance to the twists of the plot. This book is therefore necessary to understanding the trilogy and is less interesting than the first two parts. Therefore looks forward to the sequel that will hopefully closer to the magic and fantasy that were present in the pages of the two previous volumes.
