Twenty Thousand Leagues Under the Sea by Jules Verne
My rating: 5 of 5 stars
This is definitely one of the best classic science fiction I've read so far. I was amazed that Verne might have started the idea of the submarine and the under the sea explorations. While I was reading this, I was contemplating where he got his ideas or whether silly it might be, he could have time traveled from his time to the future or vice versa.
