In the shop we buy and sell them, but in truth books have no... - Carlos Ruiz Zafón, The Shadow of the Wind

"Every book, every volume you see here, has a soul. The soul of the person who wrote it and of those who read it and lived and dreamed with it. Every time a book changes hands, every time someone runs his eyes down its pages, its spirit grows and strengthens."

"Few things are more deceptive than memories."

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

"A story is a letter that the author writes to himself, to tell himself things that he would be unable to discover otherwise."

"As it unfolded, the structure of the story began to remind me of one of those Russian dolls that contain innumerable ever-smaller dolls within. Step by step the narrative split into a thousand stories, as if it had entered a gallery of mirrors, its identity fragmented into endless reflections."
