The five Kingdom Keepers and their core friends have uncovered a startling truth: Maleficent and the Overtakers are plotting a catastrophic event that could have repercussions far beyond the world of Disney. Aboard the Disney Cruise Line’s inaugural passage through the new Panama Canal, the Keepers and their holograms uncover a puzzle hidden within the pages of a stolen journal. The point of that puzzle will reveal itself in the caves of Aruba, the zip lines of Costa Rica, and the jungles of Mexico. A destructive force, dormant for decades, is about to be unleashed. The five Kingdom Keepers are to be its first victims.
