It really sucks getting on the bad side of any of the big bads of this world. This particular book features some particularly nasty vampire infighting, with some rather serious implications for everyone else in the area (of course).
This does seem like a bit of a placeholder story – nothing is particularly new, just variations on some things we’ve seen before. It really feels like the set up to a chess match – certain identities are revealed, powers are clarified, and things then seem to simmer back down to normal. I do hope this is setting up something epic.
