In terms of writing, we feel that the main target is the youngest, but personally it did not bother me because it still remains open to the greatest. This is not a youth reading "boat" as we sometimes found, there is a true story, stories that intertwine and a heroine who tries to untangle. The truth about what really happened is thus given us little by little, which maintains great mystery pleasantly while punctuating the narrative.
The characters are meanwhile well chosen. Isabelle has an interesting personality and it is a character that is pleasant to follow. His brother against me by a little less hooked, yet it is not trivial but I was more sensitive to his sister!
Finally, here is a nice reading that makes you want to discover Brittany (even if it rains more than half of the novel!). I really was moved by the story and I can not wait to read Volume 2, released in France on September 15, 2011, to regain Isabelle and following his adventures.
