Decent conclusion. I didn't feel the series petered out or wrapped everything up too neatly, like I do with a lot of trilogies. Not that I go around reading trilogies, I'm just saying.
The overall story humans vs Darklings arch had a nice twist in this book, and the ending was pretty interesting, if a little head-scratchy. I don't want to get all spoilery about it, so I guess Meg or Ames can expect emails from me soon.
This isn't a "review" as much as "notes to myself for years down the road when I can't remember if I read this book or not." But I did. I did read this book.
