They all fell silent, looking rather scared; the problem facing them seemed insurmountable.

“Well, we’ll have to fly, won’t we?” said Luna, in the closest thing to a matter-of-fact voice Harry had ever heard her use.

“OK,” said Harry irritably, rounding on her. “First of all, ‘we’ aren’t doing anything if you’re including yourself in that, and second of all, Ron’s the only one with a broomstick that isn’t being guarded by a security troll, so—”

“I’ve got a broom!” said Ginny.

“Yeah, but you’re not coming,” said Ron angrily.

“Excuse me, but I care what happens to Sirius as much as you do!” said Ginny, her jaw set so that her resemblance to Fred and George was suddenly striking.

“You’re too—” Harry began, but Ginny said fiercely, “I’m three years older than you were when you fought You-Know-Who over the Philosopher’s Stone, and it’s because of me that Malfoy’s stuck back in Umbridge’s office with giant flying bogies attacking him—”

“Yeah, but—”

“We were all in the D.A. together,” said Neville quietly. “It was all supposed to be about fighting You-Know-Who, wasn’t it? And this is the first chance we’ve had to do something real—or was that all just a game or something?”

“No—of course it wasn’t—” said Harry impatiently.

“Then we should come too,” said Neville simply. “We want to help.”

“That’s right,” said Luna, smiling happily.

Harry’s eyes met Ron’s. He knew Ron was thinking exactly what he was: if he could have chosen any members of the D.A., in addition to himself, Ron and Hermione, to join him in the attempt to rescue Sirius, he would not have picked Ginny, Neville or Luna.

“Well, it doesn’t matter, anyway,” said Harry through gritted teeth, “because we still don’t know how to get there—”

“I thought we’d settled that,” said Luna maddeningly. “We’re flying!”

“Look,” said Ron, barely containing his anger, “you might be able to fly without a broomstick but the rest of us can’t sprout wings whenever we—”

“There are ways of flying other than with broomsticks,” said Luna serenely.

“I ’s’pose we’re going to ride on the back of the Kacky Snorgle or whatever it is?” Ron demanded.

“The Crumple-Horned Snorkack can’t fly,” said Luna in a dignified voice, “but they can, and Hagrid says they’re very good at finding places their riders are looking for.”
