It is many years now that I read this volume, but I remember perfectly to have previously devoured the entire series. The end is moving in some aspects but all the plot elements of the series do not disappear. Thus we learn in the book he has there some kind of new organization but we do not know who they are, what they do and they are their goals where the question: why we put this item if c is to stay on our hunger? Also coincidentally orphans fall on an island where they fail and by who knows what miracle the head of the island is other than a member of the organization were part of parents Baudelaires orphans no hand-holder who either (lack of realism ...).
Notice that the series with a thirteenth volume, which is a number brings bad luck ... All meaning is in itself;)
