The Ghost Grabbers (an internet program, and Jaden's heroes) are filming a seance at the Pendleton Public Library, where the recently discovered unpublished manuscripts of the late horror author and library founder Alistair Pendleton are on display--so when the lights go out, and the manuscripts disappear, Jaden (who thinks a ghost took them), his twin sister Hayden, and the other members of Snoops Inc. swing into action to solve the mystery.
