Your fingers brush the spine of your favorite Nancy Drew book, and you can't stop yourself from cracking it open. As soon as you do, a rushing sound fills the air. The light in the room suddenly becomes blinding, and you can't see anything. An odd, tingling sensation sweeps through your body, and the floor seems to be shaking--

You snap the book shut. Your heart thumps against your chest as you throw it down. Your hands shake as you turn toward the door, all thoughts of retrieving your book gone. You've felt uneasy the entire time you've been here, and you're not going to stay a second longer after that . You race down the stairs and out the door, stuffing your still-shaking hands into your pockets.
