So second book of the series and I think in certain respect it is better than the first one. However it is not a book I would go back and read again. It is a nice read when you read it for the first time and then you forget about it. Just like the first book of the series there is hardly a paragraph you will ever look back to. The language is so plain it that kills the fun. At times I felt like putting the book down and start reading a new one. That was okay though, the biggest problem for me is that I am done with two books and still there is not a single character in the book I remotely care about. Vin is the main protagonist and whenever she is fighting I want her to win and I want her to kill everyone else. But when she is hurt there is no concern for her. That is with the most important character, how do you think things are with the other people? Sanderson doesn't make you care for the character. About 1400 pages in the story and the only character I remotely care about is Kelsier, and he died in the first book.
The second book has another feature which I found to be extremely irritating. I understand that he wants his reader to know what happened in the first book but dedicating one paragraph for every incidence that happened in the first book is way too much. Then there was this description of powers. He described all of them in his second book and yet in the second book every time Sazed uses Feruchemy he starts explaining how Feruchemy works. We get it Brandon, we got it the first time you explained it to us in the first book. And it was nice reading it in the first few chapters of second book but it was plainly irritating to read it every time someone uses it.
To be fair though, the book had some decent twists. A few instances which took by surprising. Nothing of the sort though where you go "Whoa, WTF happened there."
And despite what some say definitely not as good as A Song of Ice and Fire. In fact it compares no where to ASOIF in terms of complexity and intricacies.
