Thirteen-year-old Finn Whitman and four other young teens have been transformed into holgorams to be guides for visitors to Disney World. When Finn is unexpectedly transported to the Magic Kingdom in his hologram form, Wayne, an Imagineer, tells him that he and the other guides must save the park from the scheming witch Maleficent and the Overtakers.

For the five teens who modeled as Disney Hologram Imaging hosts, life is settling down when an intriguing video arrives. The Overtakers are plotting to attempt a rescue of two of their leaders, both of whom the Disney Imagineers have hidden away somewhere following a violent encounter in EPCOT. An attack by new Overtakers at Downtown Disney startles the group. A dark cloud in the Kingdom Keeper era is unfolding, and with dissension in the ranks, it's...

The Kingdom Keepers, five teens who've 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.

The Kingdom Keepers have their hands full when, during the inaugural cruise of the Disney ship, Fantasy, to exotic locations, they discover that the Overtakers have infiltrated the cast, stolen a journal that belonged to Walt Disney himself, and plan to unleash a powerful evil, the Chernabog.
