A field trip brings Cordelia, Benji, and Agnes face-to-face with a dangerous phantom—a ghost capable of reanimating dead animals—and a team of professional ghost hunters that disappear right after they capture the phantom. Cordelia can’t help herself—she needs to know more about the ghost hunters and the phantom.
It’ll mean getting Agnes and Benji to join her and the ghost hunters at a strange village called Shady Rest where ghosts live peacefully in their own homes. But soon, Cordelia, Benji, and Agnes realize that Shady Rest is not quite what it seems. Ghosts are disappearing from their homes. Others start to glow and grow frighteningly long necks and extra teeth. And some of them look strangely familiar. Didn’t they save these ghosts already?
