I cheated and looked up the Wikipedia entry that has plot synopses and now I have even less interest in finishing it. You can only play "which side is this person on" for so long before you get to the point of saying "you know what? I don't even care now." And TMITHC seems to do that with almost ALL of the main characters (Juliana, Joe, Kido, Smith, etc.) It starts off as interesting but with no "payoff" or resolution it just gets tiresome.
I'm not sure anyone could have done better. Maybe if they hadn't cribbed the title and the premise from a Philip K. Dick novel and just struck out with something new it might have been better but who knows. You can only take that premise so far before it becomes ridiculous.
