The series continues strong. Probably it’d be stronger if I hadn’t had such a gap between 3 and 4. The illustrations are up to their usual quality, and the story progresses at a reasonable pace. It turns out I’d forgotten who two of the characters were and where they came from, but aside from that, I enjoyed the volume as much as the previous. The one quibble I have is that the timing of some of Nina’s actions was a little unclear to me.
