Super Tuesday For Teens and Tweens

John Sellers of PW's Childrens Bookshelf recently compiled a list of books for kids of all ages related to the election in Children's Publishers Stuff The Ballot Box. I culled the list for tween and teen appropriate fiction (you'll notice a couple of familiar titles on the list if you're a Fire Escape regular):
  • First Boy by Gary Schmidt (Square Fish, ages 12-up).
I'm not quite sure how the powers that be figure out the age appropriateness of novels (my two books differ, for example, and I have no idea why).  Any additions to the list?
