Cornelia Funke said this quote

Elinor had read countless stories in which the main characters fell sick at some point because they were so unhappy. She had always thought that a very romantic idea, but she’d dismissed it as a pure invention of the world of books. All those wilting heroes and heroines who suddenly gave up the ghost just because of unrequited love or longing for something they’d lost! Elinor had always enjoyed their sufferings—as a reader will. After all, that was what you wanted from books: great emotions you’d never felt yourself, pain you could leave behind by closing the book if it got too bad. Death and destruction felt deliciously real conjured up with the right words, and you could leave them behind between the pages as you pleased, at no cost or risk to yourself.
