Ghoul Games (Goosebumps House of Shivers #9)

House of Shivers is the most thrilling Goosebumps series yet! Cindy Smith is excited when a couple of new kids move in across the street. But she's not sure what to think of them. They seem a little strange. . . maybe even monstrous. The new kids, Retch and Heeve, have a secret--they are actual monsters who are about to graduate from Ghoul School. In order to earn their diploma, they have to terrify some real-life humans. Will Cindy be scared silly, or are the ghouls doomed to flunk out?!
