Harry Potter sat quietly in the corner of the Hogwarts library, watching rain fall against the tall windows. He had been searching for an old spell when he noticed a small, dusty book hidden behind a row of books. When he opened it, the pages were completely blank—until his fingers touched the first page. Suddenly, glowing words appeared: “What you seek is not in this book, but where you are afraid to look.” Harry looked around nervously. A soft whisper came from somewhere behind him. He closed the book, grabbed his wand, and followed the sound into a dark corridor he had never seen before.
