I am a little mixed about this book. It started off really slow, and had to use a lot of exposition. It also employed a lot of 'soul-searching', which can be annoying. I also was finding the main character to be a little 'Mary-Sue'-ish. If I hadn't already bought the next book, I'd have probably given up.
Then, in about the last third of the book, the action really picked up. There were plenty of plot twists, and Vin redeems herself in a big way, not by being wonderful and right, but by doing what she needed to do, and following her conscience.
Looking much more forward to the next installment!
