Possible SPOILERS, I guess.
I’ve been a huge fan of the series all along, and this one didn’t disappoint at all.
I think what I’m becoming most impressed with is the increasing dark tone of the Series. Admittedly, it wasn’t all sweetness and light ever. But there was a sort of humor in the first couple of books that’s been draining away gradually – not that the intrinsic humor of the writing has gone away, in fact it has even improved – but the children no longer get any rest. There isn’t a time to just sit back, invent, read, talk, bite, whatever.
I’m also astounded at the depth of the moral angle of the books. This one deals with how we treat those differently from ourselves, media extremism, and how sometimes people participate in their own victimization without ever once playing the after school special.
And the children are having to face up to the moral implications of their actions. In order to beat Olaf, they’ve stolen, lied, committed arson, and perhaps caused death through inaction. I don’t think the author is going to allow the children to completely walk away from this, and it makes me even more excited to know where the ending is really going to lead.
