Plot
During the American Civil War, five Union Army prisoners escape their Confederate captors in Richmond, Virginia, by hijacking a hot air balloon. After flying for days in a storm, they crash-land on an uncharted volcanic island in the South Pacific. The castaways name it “Lincoln Island” and, under the leadership of engineer Cyrus Smith, manage to survive by applying their skills and ingenuity to create a thriving colony.
As they settle on the island, the group experiences a series of seemingly inexplicable events and mysterious happenings. They rescue another castaway named Ayrton from a nearby island, fight off a group of pirates, and receive aid from an unseen benefactor. The colonists also domesticate an orangutan they name Jup and construct an impressive array of equipment and structures, including a seaworthy ship.
Eventually, the castaways discover their mysterious benefactor is none other than Captain Nemo, who has been living in secret on the island with his submarine, the Nautilus. On his deathbed, Nemo reveals his true identity as an Indian prince and explains how he has been helping the colonists. He leaves them a chest full of treasure before passing away.
In the novel's climax, Lincoln Island's volcano begins to erupt. The colonists, forewarned by Nemo, take shelter on the last remaining piece of land above sea level. They are ultimately rescued by a passing ship that Nemo had previously contacted. Using the treasure Nemo left them, the group returns to the United States and establishes a new colony in Iowa.

Setting
Opening during the American Civil War in the 1860s, The Mysterious Island primarily takes place on an uncharted volcanic island, which the castaways, five former Union Army prisoners of war, name “Lincoln Island” in honor of President Abraham Lincoln. This remote landmass becomes the protagonists' home and the center of their extraordinary adventures.
Lincoln Island is described as being located roughly 2,500 kilometers east of New Zealand, in the southern Pacific Ocean. While isolated, the island proves to be a microcosm of diverse environments, featuring everything from dense forests and sandy beaches to towering cliffs and a central volcano. This varied landscape provides the castaways with both challenges and resources as they struggle to survive and build a new life.
Beyond Lincoln Island, the action briefly shifts to nearby Tabor Island, where the group rescues another castaway. The story also touches on the vast undersea realm explored by Captain Nemo in his submarine, the Nautilus, linking The Mysterious Island to Verne's earlier work, 20,000 Leagues Under the Sea. This connection expands the geographical scope of the novel, hinting at the mysteries lurking beneath the ocean's surface and tying the island's fate to Nemo's hidden base.

About the Author
Jules Verne (1828-1905) was a pioneering French author best known for his novels of futuristic adventure. His most famous works include 20,000 Leagues Under the Sea, Journey to the Center of the Earth, and Around the World in 80 Days. Verne is considered one of the founders of science fiction, though he viewed his works more as “geographical fiction” aimed at educating readers about the world in an entertaining way. While often hailed as a technological “prophet," Verne attributed any accurate predictions in his novels to his thorough research.
Verne's partnership with publisher Pierre-Jules Hetzel led to the creation of the Voyages Extraordinaires series, which eventually included over 50 novels. These stories combined scientific knowledge with imaginative adventure plots, often featuring futuristic technologies. Though initially dismissed by literary critics as genre fiction for children, Verne's works have since gained recognition for their literary merit and influence on avant-garde French writers.
Verne's influence extends far beyond literature. His novels inspired many scientists and explorers, including submarine designer Simon Lake and rocket pioneer Wernher von Braun. Verne is also credited with helping inspire the steampunk genre. As Ray Bradbury noted, “We are all, in one way or another, the children of Jules Verne.”
