Pros - Very unique and unusual protagonist. Western. Gritty western feel. Enjoyable action. An absolutely fantastic monster villain, when we finally get to him. 
 Cons - Wandery. I prefer books with tighter narratives and this is more a series of random small encounters than it is an ongoing plot arch. Nettie is really unlikable at first, and her anger and distrust of everyone make her hard to warm to as a heroine.
