What if you only had one hundred words to warn humanity of a deadly danger? What if your favorite sci-fi movie suddenly turned into a real-life worst nightmare? What if a girl you've never seen before keeps showing up in photos on your cell phone? What if you hear a knocking sound in the middle of the night? In each of the 27 tales in this book, people are afraid. Very afraid. Read their stories. See if you share their fears. Because if you don't now . . . you will.
