I really love middle-grade. Middle-grade books have a little more of a magical, light-hearted feel. You can be a little bit more quirky, you can have a little more humor. It doesn't get so dark and deep.

She and Thomas had helped construct the Maze; at the same time she’d exerted a lot of effort to build a wall holding back her emotions.

I've always been fascinated by quantum physics and the possibility of alternate realities.
