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.
