The Kingdom Keepers 2: Disney at Dawn
The Second installment of The Kingdom Keepers. It is supposed to be out around August 26,2008, according to Ridley's Blog.
Disney at Dawn
It's supposed to be a happy day at the Magic Kingdom – the return of the teenage, holographic hosts. But things go very wrong when a sudden lightning storm disrupts the celebration, and Amanda's mysterious sister, Jess, disappears. The only clue is the sighting of a wild monkey in the Magic Kingdom during the storm.
The mystery deepens as Finn is contacted by Wayne, an old man he hasn't heard from in months. Wayne tells Finn that there's trouble at the Animal Kingdom: the evil Overtakers have gained control of one of the computer servers that will be used to operate Daylight Holographic Imaging there. That means that if any of the holographic hosts fall asleep, they will go into comas – permanently.
With time running out, Finn, Philby, and Maybeck, along with Willa and Charlene, and Amanda, begin a desperate search, following a string of cryptic clues found inside the diary of the missing Jess. They must find and destroy the second server before they fall asleep; their survival -- and the future of the parks – depend on their success.
Filled with action and brimming with the same meticulous detail as Kingdom Keepers: Disney After Dark, this second book in the series — Disney At Dawn --is the result of hands-on research behind the scenes at the Animal Kingdom. Young and older readers alike will get a glimpse into a second Disney kingdom. The wild rides have only just begun; and the clock is ticking. How long can the teens keep themselves awake in their quest to find their friend — and what happens if they fail?
I personally can't wait! If you look at
http://en.wikipedia.org/wiki/The_Kingdom_Keepers, there is also some pretty cool Trivia and Mistakes you might not have noticed. I found it quite interesting.
Enjoy.
