I have mixed feelings about this one. Lee does not conform to the usual spoon-feeding of background info through long swathes of explanation or dialogue. In fact, he assumes you can figure it out and marches on with the story without explaining how the magic works. Kudos to him for skipping exposition. He also does a masterful job of presenting his factions as what they are. Additionally, there were lovely slice of life moments.
However, there are times when he jumos POV, and it's very difficult to keep up with what's going on during those jumps. I kept feeling like I had missed a paragraph or two.
Overall, the book is enjoyable, interesting, and has a solid universe. I could have wished for a tiny bit more hand-holding from Lee, as that's really where the book fell down, but it was definitely worth my time.
