He imagined the library, stripped bare, the precious books rescued by bookworms like himself. His grin widened, a secret plan already forming in his head. He'd need a good bag, some snacks…maybe a tiny flashlight.

He caught a glimpse of his own reflection in a window, a wild, untamed glint in his eyes. He grinned. He was definitely going to have a party.
