This fun, thrilling adventure story has echoes of "War Games" (the Matthew Broderick film) as it follows two scrappy kids, Katie and David Bowden, on a race across country ahead of a group of terrorists to find their reclusive, inventor uncle--the only one who might be able to help them locate their kidnapped parents, taken for the government secrets they posses of a technology called ROVER that can locate anyone in the world. It is a fast-paced, page-turning tale.
