Harry Potter and the Prisoner of Azkaban (Harry Potter, #3)

by J.K. Rowling

“The dementors affect you worse than the others because there are horrors in your past that the others don’t have.”

“I solemnly swear that I am up to no good.”

“Mr. Wormtail bids Professor Snape good day, and advises him to wash his hair, the slimeball.”

“You think the dead we have loved ever truly leave us? You think that we don’t recall them more clearly than ever in times of great trouble? Your father is alive in you, Harry, and shows himself most plainly when you have need of him. How else could you produce that particular Patronus? Prongs rode again last night.”
