Tassie - Cait has read a lot this year while "avoiding" the Twilight books. She's reading Harry Potter again right now at the recommendation of a friend who said it reads differently the 2nd time when you actually know stuff.
Some of the series she's read and still waits for the "next book" to come out:
Percy Jackson & the Olympians
Those are what I can think of now. I'll ask her for any others and get back to you.
