I saw this story as more of an excuse to do some truly excellent world-building than as a story in its own right.
And the world building was magnificent. It's a beautiful world I would want to revisit, perhaps in a full length novel.
I caught on pretty quickly to the idea of several different characters all converging on the Nexus (get it?) at the right time to ensure that the Architect can begin fixing the City.
At first I was confused as to the purpose of the Librarian. Really? He was there to throw a thingy at the bad guy?
But then I realized that his job was perhaps the most crucial. If the Architect is in charge of the physical buildings, the Guard is to protect the City and the Silhouette is to be its conscience, what's left for the Librarian? He has the most important job of all. He must fix the City's
narrativium. Without it, the City and all its inhabitants would crumble, face chaos and be destroyed.
All in all, an excellent story and an excellent reading (as always) by Mr. Dunlop. (Even though he had a little snrrk in there).
Also, I want a lensegear for <insert winter gift-giving holiday here>.
