20000 Leagues Under the Sea 

20,000 Leagues Under the Seas is about the adventures of Captain Nemo and his crew aboard the submarine, Nautilus. One day ships start sinking, particularly ones dealing with war. Survivors think it is a big whale. A harpoon ship goes out to kill it, but finds out that the whale is actually the Nautilus.
The most interesting part of this book was probably the Nautilus itself. It is shaped to look like a fish, with a large metal fin on top used to ram and sink the ships. The camouflage of the boat being shaped like a whale works, up until the part where the Nautilus takes on a few passengers from one of the sinking ships.
Another intriguing part of this book was Captain Nemo. He is the kind of character that you neither like nor dislike. I say this, because of some of Nemo’s actions. Captain Nemo hates war, and throughout the book, he uses his submarine to destroy all kinds of war related ships. You would like him for trying to put an end to war, but dislike his method (destroying ships and killing inn
In the year 1868, rumors of a sea monster attacking ships in the Pacific Ocean have created apprehension and fear among sailors, disrupting the shipping lanes. Prof. Pierre M. Aronnax and his assistant, Conseil, are on their way to Saigon but get stuck in San Francisco by the halting of ships. The U.S. government invites Aronnax onto an expedition to either prove or disprove the monster's existence. One of their fellow crew is the cocky master harpooneer Ned Land.
After months of fruitless searching, the monster is spotted one night. It immediately charges, and the ship's crew are only able to fire cannons at the monster a few times before impact. Ned and Aronnax are thrown overboard, and Conseil goes in after Aronnax. The warship, burning and helpless, drifts silently and no one on board answers when the overboard passengers cry for help. The three drift in the ocean, eventually finding a strange-looking metal vessel, and realize the "monster" is a man-made "submerging boat", that seems to have been deserted. Inside, Aronnax wanders down into the Salon, where he finds a massive viewing window and sees an underwater funeral taking place, presumably for a man on the submerging boat who was killed by the expeditionary ship's guns.
When the submarine crew returns to their ship, they capture the three castaways. The captain introduces himself as Nemo, master of the Nautilus. He returns Ned and Conseil to the deck, while Aronnax, whom he recognizes for his work and research, is allowed to stay. He tempts Aronnax to remain with him, but Aronnax prefers to share his companions' fate. Nemo prepares to submerge Nautilus with the three stowaways on the deck, but at the last moment changes his mind and allows them to stay. After dinner that night, Nemo takes them all on an underwater expedition to gather supplies, but Ned tries to salvage a treasure chest from a sunken wreck, almost getting attacked by a shark.
Later on, Nemo takes Aronnax to the penal colony island of Rura Penthe. Nemo reveals he was once a prisoner there himself, as were many of the crew of the Nautilus. A munitions ship embarks at sunset, whereupon the Nautilus rams it, destroying its munitions cargo and killing the entire crew. When confronted by Aronnax, Nemo claims that his actions have just saved thousands from death in war; he also discloses that this "hated nation" had killed his wife and son in an attempt to force him to reveal the secrets of his work. Meanwhile, Ned discovers the coordinates of Nemo's secret island base, Vulcania, and releases messages in bottles, hoping somebody will find them and free him from captivity.
Off the coast of New Guinea, the Nautilus gets stranded on a reef. Ned is surprised when Nemo freely allows him to go ashore with Conseil, ostensibly to collect specimens. Ned goes off alone inland to explore avenues of escape. While kneeling at a pool to drink he sees a number of human skulls on stakes. Unbeknownst to him he has been spotted by a cannibal in a nearby tree. Realizing his danger, Ned runs for his life and rejoins Conseil as they are chased back to the Nautilus. Despite remaining aground, Nemo is unconcerned and the cannibals are repelled from the ship by electrical charges circulated on its hull. Captain Nemo is furious at Ned for not following his orders, and confines him to the submarine's brig as punishment.
A warship approaches, firing and striking the submarine just as it breaks free of the reef. It descends into the depths, where it attracts the attentions of a giant squid. The electric charge fails to repel the monster, so Nemo and his men are forced to surface in order to fight and dislodge the beast. During the battle, Nemo is caught in one of the squid's tentacles; Ned, having escaped from captivity in the struggle and in spite of his hatred for the captain (due to experiencing the destruction of the munitions ship from earlier), jumps to Nemo's rescue and saves his captor's life. As a result, Nemo has a change of heart; he claims now to want to make peace with the outer world, by sharing his secrets of the sea. However, this is to be short-lived.
As the Nautilus nears Vulcania, Nemo finds the island surrounded by warships, whose marines are converging on his hideout. As Nemo goes ashore, Ned attempts to identify himself as the author of the bottled messages to no avail. Aronnax realizes this and becomes furious, recognizing that Nemo will destroy all evidence of his discoveries. Sure enough, Nemo plants a bomb in his hideout, but is mortally wounded from a slug to the back while returning to the Nautilus. After haphazardly navigating the submarine away from Vulcania, Nemo announces he will be "taking the Nautilus down for the last time." Loyal to Nemo to the very end, his entire crew declare that they will accompany their captain in death.
Aronnax, Conseil, and Ned are taken forcibly to their cabins. Ned fights back, escapes to the now deserted bridge, and manages to surface the Nautilus, hitting a reef in the process and causing the ship to begin flooding rapidly. In his final moments, Nemo staggers to a viewing window, collapses, and looks at his beloved ocean one last time as he dies.
Aronnax tries to go back and retrieve his journal, which contains a detailed account of the voyage, but the urgency of their escape obliges Ned to knock him unconscious and carry him out. The companions witness Vulcania destroyed in an explosion. Aronnax's diary of the voyage is also lost forever, and when Ned apologizes for having hit him, the Professor replies "Perhaps you did mankind a service, Ned". The shock from the explosion causes the Nautilus to sink even more quickly, and as it disappears beneath the waves forever, Nemo's last words to Aronnax echo: "There is hope for the future. And when the world is ready for a new and better life, all this will someday come to pass, in God's good time."
