My library has this shelved in the juvenile section, but I'd be pretty hesitant to actually suggest this one to anyone in elementary school. For the record, that's because I fear the wrath of parents, not because I actually think children would be damaged by reading "adult content".
Anyway, ugh, I am so disappointed. In the copy of this that I read, there was a preview chapter for another of Donna Jo Napoli's books at end of the story, and it was like being hit with a hammer. I was totally not expecting the book to be over, because NOTHING WAS RESOLVED.
I mean, I don't need a tidy ending where everything ends happily and all the answers are given. But I do expect a few answers, you know, to the lingering questions that have been in play since the first third of the novel. Gah. I feel like that was a waste of time.
