Quick, fun read that is much more tonally consistent than other Buffy books I've read lately. I liked the idea of Hellmouth pests as well: that ecological spillover from another dimension is enough to cause chaos when said demon pests don't do well in a new environment. It makes a change that the Big Bad isn't actually a Big Bad at all, just a bunch of little critters doing their thing, without an evil plan to their name. The kur was an interesting idea too, but I thought the wee salamander was cuter (aside from the whole burn-you-from-the-inside-out thing).
