The Secret of Rover
The Secret of Rover follows the clever and resourceful twins Katie and David as they race across the country in their attempt to outwit an international team of insurgents who hold their parents and baby sister captive in a foreign land. Held hostage because they invented a spy technology called Rover that can locate anyone in the world, Katie and David's parents are in grave danger. Now, it's up to Katie and David to rescue them. But first they must find their reclusive uncle, whom they have never met—the only person they know who can help them.
