Terminal World is classified as a steampunk book. I agree with that but it has a large amount of future in it so it also is science fiction for me.

Terminal World was worth reading. We meet all kinds of fascinating people and not-people in the story, which starts in a very complicated, high structure called Spearpoint. As the story progresses, steampunk becomes more prominent (steam, airships etc). The pace of the story is good, I like how it flowed along, and also the way Mr Reynolds managed to express himself in descriptions is very nice. At some point in the story I feared that things would turn into a ‘Mad Max’ environment as the Skullboys made their appearance but that proved to be not so. Such a relief.
The end of this book was very good, amazing in some places even (I name Tulwar and Nimcha in particular). And I definitely liked the Mad Machines.

If you are in search of a great story to read, I can recommend Terminal World.
