A number of elements combine to render Jules Verne's best works truly remarkable; they are at once informative, innovative, dramatic, and funny. Unfortunately, "The Steam House" does not belong to Verne's best works...
-Informative-
Verne was up-to-date on the latest technology ("20,000 Leagues Under the Sea") and also drew back the curtain on far-flung places his readers would probably never get to visit themselves ("Around the World in 80 Days"). While he certainly provides lots of information on India in "The Steam House," it's not particularly interesting, but rather what you might find in the first two paragraphs of a travel guide or Wikipedia article. Except, the information is now 150 years out-of-date, and my own paucity of knowledge about India means I haven't got much to compare it with.
-Innovative-
Verne had the exciting ability to take the most modern technology and craft a story that took it several stages farther. "The Steam House" scores fairly well on this metric, as Verne basically predicted RVs, sending his protagonists on a road trip in something that could quite literally be described as a "mobile home," consisting as it does of two actual houses pulled by a steam-powered elephant. As he correctly guesses, this combines the power, reliability, and comfort of railroads with the free mobility of wagons. The steam house itself was easily the most interesting aspect of the book, and it's no wonder that it made its way into the title.
-Dramatic-
An exciting concept or setting doesn't necessarily make for an exciting story, but Verne usually knew how to keep the drama moving along, with an ultimate goal, intermediate perils or challenges along the way, and plenty of unexpected twists. "The Steam House" scores horribly by this metric. The central rivalry between Captain Monro and Nana Sahib did not keep my interest whatsoever, and even IT only flared up on occasion. The majority of the book is just these guys taking a somewhat slow, somewhat boring vacation through India. The supposed plot twists and "unexpected" revelations are telegraphed from a mile away. I was not at all invested in the narrative of this book, nor in any of its characters.
-Funny-
Although Jules Verne was not a comedian, he clearly had a good sense of humor, commenting sarcastically on the world in which he found himself. Although there was good potential for this in "The Steam House" due to the fact that the narrator is a Frenchman traveling with Britons through a British colony, I found very little humor in the book. The comical character of Mathias Van Guitt brought a little sunshine in, but in payment I had to endure lengthy descriptions of tigers being killed for the sake of killing tigers. The extended accounts of war atrocities didn't make for the lightest reading, either.
In summary, there are better books by Jules Verne, and I recommend starting with them first!
Note: I listened to "The Steam House" as a Librivox audiobook.
