The Stone Sky is a nice conclusion to this series. It was sad and somber, and very technical. I was so lost in the tech, that I found myself skipping over a lot of it (paragraphs at a time). As I have said in my other reviews of this series, I am not invested in the earth magic of the orogenes and the whole silver thing was just a lot for me. It was unique and I can appreciate it, but definitely not something that held my interest. The character’s did though. I felt for everyone in the end. So much suffering and trauma with no happy ending, for anyone really. I enjoyed how it all came together. Several shockers. Good writing and wouldn’t mind reading more by NKJ, just not about earth magic.
