Jules Gabriel Verne was a French novelist, poet, and playwright best known for his adventure novels and his profound influence on the literary genre of science fiction.
Verne is generally considered a major literary author in France and most of Europe, where he has had a wide influence on the literary avant-garde and on surrealism. His reputation is markedly different in Anglophone regions, where he has often been labeled a writer of genre fiction or children's books, not least because of the highly abridged and altered translations in which his novels are often reprinted.
This book is a sequel to Twenty Thousand Leagues Under The Sea. A party of British adventurers, who had been ballooning, but whose trip had ended by being cast away on a Pacific island, have various setbacks due to both pirates and convicts who had escaped from jails in mainland Australasia. They realise that at times there appears to be some kind of entity that is looking after them.
