Hello, new guy here, so I'm probably repeating things already said.
I love the fact that the author of the review is positive about the book, but I have a couple of issues with it (the review).
As Jeff In Boston (raisindot) says, half of the review is wasted on DW backstory. As much as I'd like to get more people into the DW canon, I don't think the 37th book is the best place to start. (I do note the reviewer says it's inside-baseball, but I don't think that's a real expression!)
I noted that: "he's let the trolls, vampires, medusae, dwarves, werewolves, zombies, and assorted other nonhumans into the city". Please correct me if I'm wrong, but I don't recall any medusae ever taking up residence in Ankk-Morkpork?
There's also no regognition that Discworld football bares a strong resemblance to our medieval football, when teams fought to take the ball between villages.
Any how, I'm niggling now, and I should really be in bed. I look forward to finding out the inevitable mistakes I've made :p
While I'm still confused and uncertain, it's on a much higher plane, d'you see, and at least I know I'm bewildered about the really fundamental and important facts of the universe.
