Shadow Scale was an incredible expansion to the first novel in the series. The plot takes on a new focus, and to reflect that the structure becomes much more of an adventure than it ever was before. I loved the world building, and the character development, and the places in which the main characters have to come to term with their own devastating failures. There were a few things I didn't like as much too; the ending was much less satisfying to me, and I took issue with the way the love interest acted. But despite that, I adored the way the series brought all of its pieces together, and Glisselda's development was the best thing I could have hoped for. I only wish it was explored further than it was.
