Too much felt like it had been jammed in without a second lookover and gotten past an editor.
Trying to figure out if the back-to-back introduction of goblins and orcs is a build-up to a Tolkien Shout Out
where it turns out they're the same species. Otherwise, it seems strange to have both races suddenly show up in the 'verse. (Which is not to say that the goblins aren't interestingly developed and well-done.)
I really hope he doesn't go too much further with Vimes and the Summoning Dark. I *like* Vimes when he's being a Badass Normal
. The Summoning Dark looked like lazy storytelling and occasionally a Deus Ex Machina
so Vimes would find out things he otherwise couldn't know. Shouldn't the Guarding Dark in Vimes's head be doing something about this?
Vetinari also seemed slightly off- his attention was on the wrong details. Part of me wonders if he's an Author Avatar
in that regard, and Sir Terry's going to write his decline into Vetinari.
