I think that this novel is interesting and full of adventures.I also like the ending of this book because Swiss family was happy at the end.i want to include more in this novel that they live happy in the cave and find some other precious things like gold stones etc. I recommend the family should stay in the island because the island is a proper place to survive for them and they also have a home in the island the cave.☺they also have precious crystals in the cave.
