J.K. Rowling, Harry Potter and the Prisoner of Azkaban

"He was my mum and dad's best friend. He's a convicted murderer, but he's broken out of wizard prison and he's on the run. He likes to keep in touch with me, though...keep up with my news...check if I'm happy..."

"Professor Kettleburn, our Care of Magical Creatures teacher, retired at the end of last year in order to enjoy more time with his remaining limbs."

"Bad news, Harry. I've just been to see Professor McGonagall about the Firebolt. She – er, got a bit shirty with me. Told me I'd got my priorities wrong. Seemed to think I cared more about winning the Cup than I do about staying alive. Just because I told her I didn't care if it threw you off, as long as you caught the Snitch first."

"How're we getting to King's Cross tomorrow, Dad?"asked Fred as they dug into a sumptuous pudding."The Ministry's providing a couple of cars,"said Mr. Weasley.Everyone looked up at him."Why?"said Percy curiously."It's because of you, Perce,"said George seriously. "And there'll be little flags on the hoods, with HB on them-""-for Humongous Bighead,"said Fred."

"Where is Wood?"said Harry, suddenly realizing he wasn't there."Still in the showers,"said Fred. "We think he's trying to drown himself."

"I don't go looking for trouble. Trouble usually finds me."

"You can exist without your soul, you know, as long as your brain and heart are still working. But you’ll have no sense of self anymore, no memory, no . . . anything. There’s no chance at all of recovery. You’ll just — exist. As an empty shell. And your soul is gone forever . . . lost."

"I dreamed I was buying new shoes last night,"said Ron. "What d'ya think that's gonna mean?""Probably that you're going to be eaten by a giant marshmallow or something,"said Harry."

"And it's Gryfindor in possession again, as Johnson takes the Quaffle— Flint alongside her —poke him in the eye, Angelina —it was a joke, professor, it was a joke..."

"I knew I could do it all this time,” said Harry, “Because I'd already done it... does that make sense?"

"Besides, the world isn't split into good people and Death Eaters. We've all got both light and dark inside us. What matters is the part we choose to act on. That's who we really are."

"I solemnly swear that I am up to no good."

"Happiness can be found, even in the darkest of times, if one only remembers to turn on the light."
