From the back of the book:
Do you prefer your gamebooks to have less dice and more gore? Welcome to the Nightshift! Normally, you turn up at the hospital at 9PM and prepare to face whatever comes through the door. You’ve patched up gunshot wounds, plated broken bones and drained abscesses. Sometimes, you’ve spent the entire night watching TV, feeling bored and just willing the phone to ring. Waiting for something to happen. But what if something did happen? What would you do if your ordinary routine just turned upside down? In this adventure, you are not a hero. You’re just a hospital worker who’s plunged into an interactive battle against demons, witches and time itself. You're caught in the middle of a nightmare but will you be able to use your wits and survive? There’s a difference with this adventure though. There's no dice to throw and no battles to fight. You won't get through by being lucky and you definitely have no spells or swords. What will get you through to the end of the nightshift is what you already have—knowledge, skills, memory and a pencil—the best advice is that you make notes of all the evidence and hints you find! You just might make it out if you can piece together the clues and figure out the puzzles. We'll see you on the other side!
