Bernard Simonay develops highly original ideas by mixing "science" (in a very small extent in the beginning) and fantasy.
Unfortunately the trilogy loses momentum son tomes to become boring. The plot becomes increasingly farfetched, Dorian and Solyane become grotesque because of the disproportionate importance B. Simonay tries to give them awkwardly. I regret that the author moves away gradually from the relatively simple (in a good sense) that was the beginning we simply discover a fabulous world.
I read this book there are around ten years in high school and I wanted to buy it when I saw the publication in paperback, collecting two volume book (the cycle consists in origin 6 volume).
I think I'll buy the second volume (Grail), which is still interesting even if the interest of the plot declines on end. But the last volume, which is devoted to their daughter Nelvéa, is really more the blow in my opinion (I'm tired quickly and I did not bother to finish reading).
We can still note that Simonay B. addresses the disturbing subject of incest in his book and that some scenes may surprise the reader at the beginning ... but as and when we realize that there is nothing perverse in the account of the author and we accept the love between the two twins.
In conclusion, this first volume phoenix is fabulous and will surely remain one of your favorite fantasy book, we only regret that result is not up to that first game.
