Have you Heard? 
With summer vacation right around the corner and kids on break I thought I'd bring to lite a great book series called "
The Kingdom Keepers". The grade level is 5 - 8 but in earnest my husband and I have been enjoying them with our son since he was 7 years old.
"Using cutting-edge technology, five Florida teens have been transformed into Holographic Hosts at Disney World. Their images appear throughout the Magic Kingdom, giving visitors information about the various attractions. It all seems to be going well, until the participants begin having disturbing dreams that start affecting their everyday lives. They sneak in after the park has closed, and Wayne, a retired Imagineer, directs them in their fight against the Dark Side, embodied by Maleficent from Sleeping Beauty. Audio-animatronic pirates from
The Pirates of the Caribbean travel through the Magic Kingdom in the little cars from the Buzz Lightyear ride. The dolls from It's a Small World clamber into the boats and start biting the occupants. Cinderella's Castle is filled with an eye-popping array of staircases, à la Escher. There's a certain coolness factor for the notion that people could be both human and hologram at the same time, and the illicit thrill of seeing all the things you don't normally get to see (both real and imaginary) makes this a must-read for serious Disney fans."

I hope you enjoy them as much as we do!
Long lines for Magic shots too!
