This is a book with a message (environmental) and also somewhat a book of two halves - though that may have been partly because I got stalled for a bit in the middle after the main piece of action. The pace of the plot varies a lot, and it does feel a bit like the ending kind of went "argh, how do I pull all these loose ends together?". Overall I did enjoy it though, and it was nice to be reading in French again, after a fairly long break of mostly English books.
