Hacker plans to launch a new virus at Motherboard - one that will crash her hard drive once and for all so he can take over cyberspace. To stop the kids and Digit from getting in his way, he tricks them into a cybersite from which escape seems impossible. In a confounding juxtaposition of scale and size, the kids first find themselves in a land of giants - then become giants themselves in a land of little people. The kids must cope with these disparities in scale and size, and use their brainpower to escape and warn Motherboard before Hacker can launch his virus. The Big Idea: You can create an exact likeness of something--though one that is a different size--by multiplying the size of every part of your original by the same number.
