This was a solid ending to the series. Not everything ended on an as satisfactory note as I would have liked, but I guess it could have been a lot worse. 
For a storyline as dragged out as this one (seeing how it is spread out over five novels), I think the resolution to it all could have been a bit more in depth and detailed. 
Especially the final phase of "the endgame" was a bit disappointing to me. I mean, I loved how Lana and Jake haunted the town and scared the crap out of everyone, but once they got everyone out of there, it started to go downhill: the shoot-out felt tacky and impersonal. Very different from the rest of the killings before that point. I'm not quite sure why S.T. Abby chose to go down that road, but oh well. I suppose she needed an easy and quick ending to their revenge…
