20,000 Leagues Under the Sea is about the adventures of Captain Nemo, his crew, and his quests/captives on board the submarine, Nautilus. Ships of war keep getting attacked and sunk. The survivors believe it to be a large whale. A harpoon ship gets sent out to track it down and kill it, but finds out that the whale is actually the Nautilus.

During a confrontation with the harpoon ship, The Abraham Lincoln, and the Nautilus Mr. Aronnax, Conseil, and Ned Land were thrown from the Abraham Lincoln and ended up being recovered by the crew of the Nautilus. Captain Nemo knew of and respected Mr. Aronnax for his studies of marine life. Nemo allowed them to stay on the Nautilus as quests, but vowed that they would never again return to their normal lives.

My favorite part would be when Captain Nemo took the Nautilus to the south pole. Once verifying that they were indeed at the pole, and the first humans ever to be there, they turned to leave. On their way out from under the ice cap they got pinned between the cap and an iceberg that rolled over and came up from beneath them. With their limited supply of air to breath they worked relentlessly to free themselves.

One thing that I found to be a little annoying was it tended to go into great detail about ever little animal or plant they came across while in their travels. This made several parts of the book very drawn out and a little tedious to read. However, overall it was a wonderful read that I would highly recommend it to anyone. Especially anyone who appreciates a good adventure.
