Publisher's Synopsis
During the American Civil War, five Northern prisoners of war escape during the Siege of Richmond, Virginia, by hijacking a hydrogen-filled observation balloon. The escapees are Cyrus Smith, a railroad engineer in the Union army (named Cyrus Harding in Kingston's version); his ex-slave and loyal follower Neb (short for Nebuchadnezzar); Bonadventure Pencroff, a sailor (who is addressed only by his surname; in Kingston's translation, he is named Pencroft); his protégé and adopted son Harbert Brown (called Herbert in some translations); and the journalist Gedéon Spilett (Gideon Spilett in English versions). The company is completed by Cyrus' dog "Top".After flying in a great storm for several days, the group crash-lands on a cliff-bound, volcanic, unknown island, described as being located at 34°57′S 150°30′W, about 2,500 kilometres (1,600 mi) east of New Zealand. They name it "Lincoln Island" in honor of Abraham Lincoln. With the knowledge of the brilliant engineer Smith, the five are able to sustain themselves on the island, producing fire, pottery, bricks, nitroglycerin, iron, a simple electric telegraph, a cave home inside a stony cliff called "Granite House", and even a seaworthy ship, which they name the "Bonadventure".During their stay on the island, the group endures bad weather and domesticates an orangutan, Jupiter, abbreviated to Jup (or Joop, in Jordan Stump's translation). There is a mystery on the island in the form of an unseen deus ex machina, responsible for Cyrus' survival after falling from the balloon, the mysterious rescue of Top from a dugong, the appearance of a box of equipment (guns and ammunition, tools, etc.), and other seemingly inexplicable occurrences.The group finds a message in a bottle directing them to rescue a castaway on nearby Tabor Island, who is none other than Tom Ayrton (from In Search of the Castaways). On the return voyage to Lincoln Island, they lose their way in a tempest but are guided back to their course by a mysterious fire beacon.Ayrton's former companions arrive by chance on Lincoln Island and try to make it into their lair. After some fighting with the protagonists, the pirate ship is mysteriously destroyed by an explosion. Six of the pirates survive and kidnap Ayrton. When the colonists go to look for him, the pirates shoot Harbert, seriously injuring him. Harbert survives, narrowly cheating death. The colonists at first assume Ayrton has been killed, but later they find evidence that he was not instantly killed, leaving his fate uncertain. When the colonists rashly attempt to return to Granite House before Harbert fully recovers, Harbert contracts malaria but is saved by a box of quinine sulfate, which mysteriously appears on the table in Granite House. After Harbert recovers, they attempt to rescue Ayrton and destroy the pirates. They discover Ayrton at the sheepfold, and the pirates dead, without any visible wounds.
