This book is very interesting because it talks about how three guys were"kidnapped" by captain Nemo and his submarine; the Nautilus.
In the first part, they all sail looking for a "monster" and the monster ends up being the Submarine, Nautilus. They got inside and they were asked to stay in a cell but they could walk and explore the submarine but never leave the submarine.
They experience many adventures, like fighting giant squid or going to the lost city of Atlantis. But when they realize that the Nautilus is actually a submarine that attacks other ships too, they decide to escape, when they escaped they realized that they were in Europe.
I really liked the book because you can hardly predict what is going to happen next, and because i like fiction.
