Like many, I was seduced by the 4th cover ... to close the book on a sense of anger mingled consternation. Dismay at the writing style (low and flat, boring possible) before the grotesque bias of the author (the characters are phoned, the dialogues of a platitude distressing, situations themselves predictable kilometers) , anger at the feeling of having been taken for a fool including the conclusion of the book (we dare not believe it is so "easy") and especially by the author's note that considers necessary explain to readers the details he used symbolic. You never know, we might be missed ...
On the merits, the initial idea is not bad (although it is questionable to what extent the "fashion" ecological played for the editing of this book) and share a good feeling, a true environmental awareness. But the caricature applied to the protagonists and their totally empty about them to their senses. Imposing a notice so peremptory readers, without any qualification or objective argument about the dessert and probably the intention. It is much more efficient to leave everyone the opportunity to form their own opinion.
