It was supposed to be a harmless night out. Sienna had convinced Cameron, Nora, Julian, Dylan, and Avery to sneak into an old amusement park that had been abandoned for years. The gates were locked, the rides were covered in dust, and the entire place was supposed to be completely empty. At first, it was fun. They laughed, explored the arcade, took pictures, and dared each other to go deeper into the park. Then the lights came on. One by one, the rides began moving. A cheerful carnival melody echoed through the empty park. Nora looked down at her camera. A photo had appeared on the screen. It showed all six of them standing at the entrance. Except none of them remembered taking it. And in the background stood a seventh figure.
