This audiobook is narrated by an AI Voice.

Ten-year-old Matt Belmont has an amazing secret: he belongs to the secret organization, EDAM - Earth Defense Against Martians. Its mission: protect Earth from the evil clutches of the SUPER NINJA ALIEN ROBOT MONSTERS - part robot, part monster, all ninja aliens from the star system Alpha Centauri.

To combat these big, dopey aliens, Matt and his troublesome little brother, Jamie, operate gigantic Robots of their own (called Robo-suits).

When the super ninja alien robot monsters attack, Matt and Jamie are called to action. With his parents captured and EDAM's secret base in peril, Matt and Jamie find themselves alone. What they discover is a cruel, and clever, plot to take over the world - something the aliens surely couldn't have thought of all by themselves! Can two bickering brothers really overcome the forces of evil and save the world?
