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?
