Many of Verne's novels have become cultural icons for Americans though Verne was French and we read him in translation. Nevertheless, his philosophy that enlightened good will and scientific advancement would save society is so close to American idealism, he seems much more American than almost any of his contemporaries.
Everyone is familiar with Around the World in 80 Days and 20,000 Leagues. For some reason, The Mysterious Island is not read as widely. Yet, in my opinion, it is Verne's best and most rewarding novel.
The opening of Myserious Island reads a bit like a serious version of "Wizard of Oz." Cyrus, Pencroft, Herbert, Neb and Gideon, and a dog named Top make a daring escape from a Civil War prison in a balloon, but the balloon is blown way off course to an uncharted volcanic island. These men are worthy souls; Captain Cyrus is an inspiring leader, Pencroft, an earthy but hardworking sailor. Gideon is kind of a "everyman" -- observant, strong and resourceful and loving, and Herbert a young, knowlegeable naturalist. These men and their dog Top conquer the island's challenges and make the very best out of their isolation on the small island. But are they prepared for the surprises the island has for them--and the ultimate surprise in the second half of the book. The suspense keeps the reader turning the pages through a great deal of descriptive information about nature, chemistry, physics and engineering. This is classic Verne and what really put the Science in Science Fiction.
One reason Mysterious Island may not have developed the strong audience of the other Verne novels is that there is so much detail and scientific discussion. That is rough going if you have little interest in such subjects. There are abridged versions that cut a lot of the description, but frankly, the science is what I love best about the book. How Cyrus and company make nitroglycerin and use it to reshape their island home is one of my favorite chapters in sci-fi literature.
If you liked Swiss Family Robinson as a child, you would surely enjoy Mysterious Island. It's one of Verne's best works and deserves to be read.
