D.J. Schwenk is the exact opposite of most YA protagonists. That's right, she's got a brain. Also? She won't let any boy mistreat her, no matter how ridiculously good looking they might be. She's a little shy but will speak up when she has something worthwhile to say, which, honestly, is more often than she gives herself credit for--like I said, the girl has brains. She's so easy to relate to, on several levels, you can't help but root her on.
The Dairy Queen series is up there on my list of favorites now. I highly recommend it. D.J. Schwenk is my hero.
