A chap called Kelsier and his criminal associates are intent upon on bringing down the Lord Ruler, and hatch a plot to do so. Magic plays a significant role in the book, and, as in (although different to) the Way Kings, the system the author has invented is simple but works very well. Essentially, there are 8 basic metals and 2 higher metals, and these can be swallowed and burnt by mistings or mistborn. The former can only use one specific metal, the latter can burn any or all of them. Each metal has a different advantage, and some burn faster than others.
The Lord Ruler is quite interesting, and I’m glad that he wasn’t overused. The author’s use of small passages from an ancient journal recalling the Lord Ruler’s journey (before he became Lord Ruler) at the start of chapters is a small touch, but one to which I always looked forward.
Generally, the world is well-described, and the obligators and Steel Inquisitors were interesting. I think some more instances of the skaa oppression might have helped, but that’s probably a bit picky.
The last third is definitely the strongest part of the book. Along with a few unexpected twists, the pace is more rapid and events more engaging. After the initial set up of the book’s premise it feels a little slow, and although the protagonist is well-developed a few of the main characters could perhaps use a little more fleshing out.
