The positives: This is a pretty book, from cover to concept. Much of the description of paper magic I could just picture as... Well, pretty. Creative magical world building, I enjoy the idea of "bonding" to a medium to creat your magical art. 
 The Negatives: the romance. There wasn't much, and it should have been cut entirely. It was one of those "young female student falls in love with her powerful older mentor" stories, and it grosses me out. Come on. It's not romantic when a high school teacher hooks up with a student, and this isn't romantic either. This was my big (only) problem with Uprooted, too, but that book at least had the benefit of being otherwise amazing. While not bad, this book is a little dull at times, and certainly didn't have me jumping for the sequels.
