They're okay, I guess. I liked the first series, but I couldn't hold on to the second one. It's fine, I guess, but there are better things to read, right? There always is.
I don't care about reading level, or whatever.
I suggest you try reading "Life of Pi" by Yann Martel. I honestly haven't read it (and I'm going to read it after I finish posting this) but my dad threw it at my head and told me to read it. Read it for Pyonchit's head! >:U
Read Animal Farm, The Giver, and 1984 if you haven't already. Reading level = unimportant, food for thought = yes.
There's this really good book called "Perfect" (and I forget the author) about a girl who is bullemic.
:X I hope you haven't read all of those already.
