This in a wonderful story. Full of adventure. There's so many facts that the author told us along the way, so many numbers. But It wasn't boring, it just added more to the book. And it's amazingly written.
Jules Verne was an incredible writer and all his books are great. This one I read when I was a child and almost din't remember the details. So I read it now again and found the story very interesting. I could not wait to read a bit more and more. The round of the world trips people do today probably started with Verne's Mr. Fogg. Read it! ;)
