Benjamin Roy is now a zombie... well, a half-zombie to be exact. The trouble is he can't tell anyone about his new infrared vision and super-speed. Not even his best friend, Sophie. 'Cause he's pretty sure the government or the police or, even worse, his parents will lock him up if they find out. But then someone starts watching him. And following him. Somebody knows his secret. And unless Ben can figure out who it is, he'll have to start running. Or lurching really fast.
