I am currently in the process of reading the second story in the book, 'Five Weeks in a Balloon' - which is apparently Verne's first novel - after reading 'Around the World in Eighty Days', and so far have been blown away by how easy a novel from the 19th century has been to read, and particularly how enthralling. The character of Phileas Fogg never ceases to amaze with his calm etiquette and unshakeable nerve, whilst his manservant Passepartout adds a brilliant aspect of comedy to the race against time. Verne's description of the various locations around the world are also incredibly detailed, making me wonder whether he has actually been there himself or not. If not, then the man had a very accurate imagination as to what these places would look like!
So far 'Five Weeks in a Balloon' has proven to be very good, with the typical Vernian adventurer of Dr. Samuel Fergusson, his Scottish friend Dick Kennedy and servant Joe going on a journey across Africa to discover the sources of the Nile in a magnificent balloon. Be warned however, that Verne's novels do contain a lot of scientific description in the earlier stages of the books particularly, something that means practically nothing to a non-scientific person like me, but is easy enough to just read through if you also don't understand. Other than that, I would say that 'Around the World in Eighty Days' is more colourful than 'Five Weeks in a Balloon', with more interesting characters, but overall they are both brilliant novels that I would highly recommend to someone who wants to start reading classic literature.
