Finn, Maybeck, Charlene, Willa, and Philby are to attend the cruise as celebrity guests, and to perform a ribbon cutting for the DHI server to go live. The Fantasy is now the most advanced cruise ship in the world.

But all is not right below decks. Strange things are happening. Unexplained phenomena. Only the Kingdom Keepers know the truth behind their invitation: nearly every Disney villain is represented onboard the new ship: whether on its decks or in its theaters. It's believed the Over takers have infiltrated the cast and are stowaways. Worse: it is believed they have stolen an important journal that once belonged to Walt Disney himself--Finn has been having dreams about this--and that some kind of mission is planned.

The ship sets sail filled with enthusiastic guests and crew, and the battle is on in new and exotic arenas: the beaches of Castaway Cay, the caves of Aruba, the locks of the Panama Canal, Costa Rica's rain forest zip line . . . But the end game is far more complicated and intense than anything the Kingdom Keepers had planned on. If the Over takers get their way, a power will be unleashed that no one will have the ability to vanquish: Chernabog, dormant for years, is about to have his full powers restored. . . .
