I am currently reading The Well of Ascension. The second book of the mistborn series.
The book is mainly about how the main characters is trying to overthrow the empire and building a new system to make everyone equal. Also defeating the power that will eventually destroy the world. The rest of the novel have already been suggested in the first two book, and kind of gives the reader of a general idea that what the characters will be facing, but also having twist in the plot giving surprise. I personally thinks that the text sometimes is a bit confusing that each character is apart and doing their own things, then at the end came back together and closing the mystery. The novel included irony to show that how different level of people is treated unequal and unfair.
