Twas good. Not my fave in the series but good. It was interesting and random so felt sort of like a filler episode in a TV series. The explanation for how the new tri-city dynamic was set up was very helpful. The entire story shows how things should work now. In fact, I think that's literally the point of this book. Mercy gets kidnapped so that other supernatural beings and us the readers can see how the partnership with Adam as leader and protector of the humans, will work. And how everyone else connected or adjacent to it will respond as well. The little Bran twist at the end was funny. Mercy's side of things beyond being a plot device is just Mercy being Mercy finding random trouble wherever she goes. She dies wind up exploring and learning a bit more about her powers though. We get to meet Marcilia's sire whose been mentioned before so that was interesting. But yeah, not a book necessary to the series. One could skip this and still know what's going on in the next one.
