I made the same mistake. That was a disturbing book. My 8th graders LOVE it though.
Ugh, I'm not sure I would've liked it in 8th grade. I guess it's more intersting than The Scarlet Letter, though.
Funny, I'd always heard it was really violent and gory, so I was prepared for that. But I didn't think the gore was too bad... psychologically speaking, it was VERY disturbing.
I'm starting the second one tonight.
Side note: If anyone has suggestions for HAPPY books, they're welcome!!
