"I can't," Hermione said before she'd thought about it. "Ginny might be there, which means I can't do any of the research in my room. And it isn't all rubbish. The answer has to be in there somewhere."
Except she was, annoying as it was, willing to admit that it wasn't in any of the books she had with her tonight. She glowered at the books as if it was their fault, and dumped he book she'd been angry with on top of the book Ron had dumped.
The problem was, without them to distract her, all she could feel was how stressed she was, and her hands drummed on her own legs. "I hate this." She said it to no one in particular, but Ron was there, and she wasn't currently yelling at him, so she supposed she could try to talk to him.
