Oh no she'd interrupted. Oops. Derry peeked through her ginger hair sheepishly, but the librarian didn't seem annoyed or anything. She smiled back at him and nodded. "I just wondered... if you didn't have a book here... if the school can order it to borrow or if I'd have to buy it myself.." It was weird asking this with someone else present, but there you go. It was the only way Derry had been able to afford to read as much as she did her whole life - the library in her village had ordered books for her pretty much every month for her whole life... Though she got the feeling she'd never run out of things to read here... just sometimes she heard about a book that she really wanted to read.

Derry glanced over at the Ravenclaw prefect with a shy smile. Ice cream, right... umm... "Oh, no thank you..." She didn't eat ice cream much, she'd had a huge allergic reaction to a nutty topping once and since then she mainly avoided the stuff.
