From the New York Times bestselling author of The Only Good Indians, Stephen Graham Jones, comes a slasher story where a teen prank goes very wrong and all hell breaks loose in a small town. We thought we'd play a fun prank on her, and now most of us are dead. One last laugh for the summer as it winds down. One last prank just to scare a friend. Bringing a mannequin into a theater is just some harmless fun, right? Until it wakes up. Until it starts killing. Luckily, Sawyer has a plan. He’ll be a hero. He'll save everyone to the best of his ability. He'll do whatever he needs to so he can save the day. That's the thing about heroes—sometimes you have to become a monster first.
