I get out of reading this novel with the feeling of having a big meeting. A style, a tone and a construction of narrative that make this book a success. I enjoyed the use of the first person who gives the account of the density by doubling and comparing viewpoints. I was touched by the beautiful story, in the unlikely beginning, Abel and Adelaide. Finally, I found this fantastic tale of two accents of the great masters of the genre: Hoffmann and Gautier. The ending is unexpected and remarkably successful. I look after with great interest. I only regret that the voting option does not include a sixth star. So I content myself with five.
