“Stories are the wildest things of all, the monster rumbled. Stories chase and bite and hunt.”
― Patrick Ness, A Monster Calls

“But what is a dream, Conor O'Malley? the monster said, bending down so it's face was close to Conor's. Who is to say that it is not everything else that is the dream?”
― Patrick Ness, A Monster Calls

“Stories don't always have happy endings."

This stopped him. Because they didn't, did they? That's one thing the monster had definitely taught him. Stories were wild, wild animals and went off in directions you couldn't expect.”
― Patrick Ness, A Monster Calls

“Stories are wild creatures, the monster said. When you let them loose, who knows what havoc they might wreak?”
― Patrick Ness, A Monster Calls
