I didn't plan to start a new book today. In fact I opened it at 2pm...and closed it at 5:30pm, having read the entire thing in one big gulp. Garth Nix wove a mysterious web which I wanted to know the answers to. A fascinating culture, seen from the eyes of a protected "Prince" who has not been told the whole truth about his universe. There's lots of room for more stories. The cultures are complex and only touched upon. It would be interesting to see this universe from the viewpoint of other characters.
