Zombie School is the 40th book in the Give Yourself Goosebumps series.
You are transferred to an exclusive boarding school in Nevada, where all of the children are very quiet. During homeroom, your teacher, Miss Simms warns that any student breaking the rules will be given demerits and sent to the Detention Wing, where the school makes an example of "bad" students. One such student enters the room and you are shocked to see that he looks like a zombie. While Miss Simms is out of the room, you steal the monocle she wears, but discover that when you look through it there are hidden brainwashing messages all over the walls and many more of the students look like zombies. The reader must then decide whether or not to put back the monocle before the teacher notices it's missing.
You put the monocle back, but what you've seen is enough to convince you that something is seriously wrong at the school. The story focuses on your efforts to escape from the school and/or alert the authorities, as the zombies start to close in on you.
You keep the monocle. Before Miss Simms can find out who took it, the bell rings and it's time for class. You pick from a list of classes and have to survive them. This storyline is similar to the setup found in Shop Till You Drop...Dead! and You're Plant Food!.
Side story C
You end up in the forest with the "Runaways", a group of other kids who have escaped from Ranewash School. You must then help them decide what to do in order to destroy the school. This storyline can be reached through either Story A or Story B.
