Hermione gulped and reached her feet again, curling practically into Harry's side. This close, his magic was making her breathless and light-headed. Then Harry began chanting in a language Hermione didn't recognise. The air suddenly thrummed with sonic power, as though the sound of his song was a form of magic itself. Hermione decided that it probably was. She felt the frequency resonate in her very bones and every cell in her body, and her instinct was to resist it as an intrusion. But Harry's words rang with her, and she opened up to it, even offered her own magic to the ebb and flow enveloping her.
