"Thank you," Hermione replied, smiling a little. "Now that I mention it, though, maybe I should go do a bit more reading rather than attempt anymore practical magic. That's what happens when you end up in a world in which you've never read any of the books."

Moving to stand up, Hermione carefully scooped the little blue fire up in her hands, only to pause as she looked down at the other girl. "Are you cold? I don't know how long the flames will last, but if you're going to spend much time out here, you're welcome to them. They shouldn't spread, and they'll be warm when you hold them but shouldn't grow unbearably hot. If they do, I'd suggest dropping them and covering them up with dirt, since they're waterproof."
