A book of exciting adventures, exciting and rewarding. Not only is it a novel breath-but, despite the density of the book (a few hundred pages), will captivate you throughout the story without you tire a moment. Moreover, it is rewarding to the extent that it provides information on the means of survival of the castaways while exposing us the sources of wealth that nature offers us and which we are not necessarily aware given the ease of modern life today .This book is also intriguing since one discovers unexpected connections with characters from other novels of Jules Verne. I can not tell you more .. But rest assured that it is a book to read and reread with passion ... My favorite Jules Verne.
