One loves truly only once in a lifetime, Julian, even if one... - Carlos Ruiz Zafón, The Shadow of the Wind

"The moment you stop to think about whether you love someone, you've already stopped loving that person forever."

"Man...heats up like a lightbulb: red hot in the twinkling of an eye and cold again in a flash. The female, on the other hand...heats up like an iron. Slowly, over a low heat, like tasty stew. But then, once she has heated up, there's no stopping her."

"In the shop we buy and sell them, but in truth books have no owner. Every book you see here has been somebody’s best friend."

"After a while it occurred to me that between the covers of each of those books lay a boundless universe waiting to be discovered while beyond those walls, in the outside world, people allowed life to pass by in afternoons of football and radio soaps, content to do little more than gaze at their navels."

"Remember me, even if it's only in a corner and secretly. Don't let me go."
