Rating: WORTHY!
Back when the movie was out - a movie I enjoyed, but which failed at the box office in December 2018 (it made only 80% of its production budget) - you could not find this book at the library at all (they were all checked out), but recently when I went in there to look for the sequel to Philip Reeve's Railhead (which was not to be had!) Mortal Engines was sitting right there - a modest paperback, so I grabbed it. And I loved it despite its three-hundred-page reading length.
The movie follows the book closely to begin with, but then increasingly departs from it. I can see why it does, but it occurs to me that if it had followed the book more closely, it would have done better than it did. The book was beautifully done and doesn't shy away from depicting hard truth and gritty reality. Hollywood not so much, and so it's sad world when a movie makes eighty million dollars, and is still considered a failure, isn't it?!
So briefly, the story is of a future, but rather steampunk world, that when analyzed makes little sense. Cities are no longer places you go to, they're places that come after you in what's repeatedly referred to as Municipal Darwinism. It's a city-eat-city world, and this is how the cities are powered and grow: by traveling the land, hunting and wrecking other cities, absorbing their populations, and recycling their raw materials as fuel and building supplies.
The biggest problem for me was the energy requirement. I'm not saying you couldn't build something that huge and have it move, but the power required to move it would be exorbitant, and where would it come from?
This story isn't set a hundred years hence, but several thousand, after a disastrous global war. Even if society could rebuild itself and take its cities mobile, the fuel (you name it: natural gas, coal, oil) would have long run out by that time, so what are they running the cities on? It's never actually discussed, only vaguely alluded to!
We're running out of oil now, something the gas-guzzling USA, with its car manufacturers ditching decent-mileage passenger cars for poor mileage SUVs and trucks while the rest of the world wisely looks to renewables. This is touched on in the story, with the USA described as an abandoned wasteland.
The story focuses on Hester Shaw, a badly-scarred young woman (the movie beautifies her giving her only a scar. She is much more disfigured in the novel), and on Tom Natsworthy, a third class historian trainee who lives in London. Hester is in a smaller village and purposefully, it turns out.
The village is absorbed by London, bringing Hester into contact with her quarry - a man named Valentine, beloved in London, but who murdered her mother. She almost manages to kill him, and then escapes by jumping into the waste chute when pursued by Tom. Inexplicably, Valentine pushes Tom down there after her, because he thinks he knows too much. I did not get that part at all - in the movie or the novel.
Tom loves London and is in denial. He forms a very uneasy relationship with Hester and each grows, over an extended time, to respect and then love the other. They have multiple adventures - more-so than in the movie - being captured twice, the second time by pirates.
The ending was very different from the movie and was amazing. I heartily commend this novel as a worthy read. There are three sequels, but I'm not sure I want to read those because I fear the first will be sullied by reading any more!
Why authors feel this need to squeeze the life out of their inventions by forcing them into ritualistic trope-filled sequels escapes me. I know it's very lucrative for publishers and authors if they can get a good pot of serial novels like this boiling, but to me it's lazy and avaricious - and abusive of readers, so I think I'll stop at this one. I had a different experience with Railhead, where I do plan on reading the next volume. Hopefully that will not become something I regret doing! LOL!
