The making of the book remains good and despite the 800 pages of the book, none is peeled from the wafer during my vacation, even with sand!
However, the French translation is poor with numerous errors. You often do gymnastics to correct the word and understand the true meaning (about 1 or 2 words every 50 pages). It spoils the pleasure of reading. As for the appendices of the book, I do not understand why the impression is so poor (we do not read on the registered places Dune plan) on volume 1 while it is perfect on volume 2 !!
I recommend you the saga but not in this version of editor.
