Using cutting-edge technology called DHI (Disney Host Interactive), the Disney Imagineers capture the images and voices of Finn Whitman, a young Orlando teen, along with four other kids, then transform them into hologram projections that guide guests through the park. The new technology turns out, however, to have unexpected effects that are thrilling and scary when Finn finds himself transported into his DHI form at night. Is it a dream or reality?...

The Kingdom Keepers, five teens who have been transformed into Holographic Hosts at Florida's Disney World, mount a search for Wayne, their missing Imagineer mentor, and find themselves fighting for their lives in imaginary worlds that have become real.

As the five Kingdom Keepers enter high school, everything is about to change. The Maintenance Base that controls all four parks in Disney World is under attack by the Overtakers, a group determined to change Disney forever. Relationships between the Keepers are no longer as simple as they once were. In fact, nothing is as simple as it once was. An after-hours visit to Typhoon Lagoon is a game changer. The Keepers lose one of their most valuable supporters....

Deception and betrayal rock the Kingdom Keepers as the merciless group of Disney villains known as the Overtakers stage an unexpected comeback, but a discovery by the Keepers provides them with one hope of victory-- a lost icon.
