Trapped in a Haunted Hotel

The elevator goes to 12. The hotel has 12 floors. So why does the display read 13? Jake and three classmates step out onto a floor that shouldn't exist — fluorescent lights, inverted carpet, and a hallway that stretches way past where the building ends. Taped to the wall: rules. Walk, don't run. Leave when it knocks. Don't look at your reflection. The rules are the only thing keeping them alive. Some of them are wrong on purpose. A survival horror novel about four kids, one impossible hotel, and the things that patrol the hallways enforcing rules nobody agreed to.
