I just got finished reading Rage-managed to get a copy of the Bachman Books-and I must say I quite enjoyed it. I personally don't agree with King's desicion to discontinue the book but I can see why he wanted to. To me there was a very thin line between good and evil here. You root for Charlie to get back at his opressors yet at the same time you want to see them help Charlie get better and you don't want to see Charlie hurt anyone else. However the people trying to help him are really corrupted or at least that's what Charlie thinks.
I loved the other characters too and sympathized with them as well. You too want to see them get away from their opressors. One part in praticular that struck a chord with me was when Sandra was talking about being "a doll" and being "real".
Personally I think this novel needs to be put back into print, it's a book that people need to read and maybe try and understand their children better.
