Alloy of Law is quite different from the previous books, but of course the setting of the novel is 300 years after the Hero of Ages. There are many new things, but still, there are also a lot of connections to the previous trilogy. 
 It's less serious book than the previous ones, and there is also a lot of humor. It was actually a nice change after the Hero of Ages, which was pretty good, but also there weren't many things to laugh about. 
 Wax and Wayne are very likable and I love the banter between them. Wayne quickly became my favourite character in the Alloy of Law. Wax is a good man and he tries to do the right thing, but he can be a little boring sometimes. But every time Wayne appears, he provides some humor and that's one of the main reasons I really like him. 
 One of the best things about this book for me was the fact that the characters had less power than Vin or Elend. That was a good change in my opinion. As much as I liked the previous books, sometimes the characters had too much power and I complained about it a little in my reviews. There are no Mistborns in the Alloy of Law, which is a little sad, but on the other hand, it's also very good in my opinion. Wax and Wayne weren't almost invincible, there were more realistic and human, and they still had some cool powers. I especially liked Wayne's "speed bubble". 
 Allow of Law is a really solid book, a mix of crime, fantasy and some western. I will be reading the next book soon:)
