The ghouls expect to have the times of their unlives partying at a gala celebrating an ancient Egyptian artefact, the comet crystal. Cleo doesn't know it, but her sister, Nefera, is planning to trick her into making a sacred promise under the light of the comet when it passes over Boo York - a promise that will change her destiny forever! And no one knows that the comet is on a collision course with the Boo World, hurtling directly toward Boo York! It's a fangtastic, claw-biting adventure that no one will ever forget . . . as long as they survive.
