Disney at Dawn by Ridley Pearson
There is a giant parade on the day the five DHI kids return to Disney World. Everyone is thrilled. It seems that everything is finally the way it should be, but then the kids notice something strange about Cinderella's Castle. When they check it out, they find the Maleficent has escaped. Now they must recapture the villain. But something else is strange as well.
The Overtakers have messed with the DHI server system. Now, if any of the teens fall asleep, they will not be able to wake up. They have also made a second server to create an animal army. But the teens soon discover that Meleficent is not the one in charge: she has a master, someone even more powerful. Can the Kingdom Keepers stop them?
Maleficent stood in the open window, her robe fluttering, the fireworks flashing colors in the sky beyond her. "Silly boys!" she said in a raspy voice. "The end is near."
