The Tale of the Virtual Nightmare (Are You Afraid of the Dark? #9)

Sam has found the ultimate game. It consumes all his time and concentration. But Sam is getting thinner, distracted. He won't even show his best friend Cady his new game. He's spending more and more time behind his locked door--until the day he doesn't come out. Cady breaks into the room. All she sees is Sam's computer with its blank screen, just waiting for her.
