Children's Lit to Start the New Year

I started the New Year by reading some stuff of my YA/IR shelf: A Wrinkle in Time and City of Ember.

Now I HAVE to go to the library and read the rest of L'Engle's series. I don't know what happened to my copies of Wind in the Door and Swiftly Tilting Planet ...

I'm not entirely sold on City of Ember. It was a bit different than I expected, and given that you can read one in a matter of hours, I guess I should just pick up the other two and finish it, too.
