In this fantastical thriller, five young teens tapped as models for theme park 'guides' find themselves pitted against Disney villains and witches that threaten both the future of Walt Disney World and the stability of the world outside its walls. Using a cutting-edge technology called DHI–which stands for both Disney Host Interactive and Daylight Hologram Imaging–Finn Whitman, an Orlando teen, and four other kids are transformed into hologram projections that guide guests through the park. The new technology turns out, however, to have unexpected effects that are both thrilling and scary. Soon Finn finds himself transported in his DHI form into the Magic Kingdom at night. Is it real? Is he dreaming? Finn's confusion only increases when he encounters Wayne, an elderly Imagineer who tells him that the park is in grave danger. Led by the scheming witch, Maleficent, a mysterious group of characters called the Overtakers is plotting to destroy Disney's beloved realm, and maybe more.
