Mind Over Antimatter

Thirteen-year-old Cole Uribe can't believe his luck when an invention contest wins him top security clearance. His mission: pose as the grandson of inventor Nicolas Araya and find Araya's plans for a micro-black-hole-powered storage device-before Alzheimer's erases Araya's mind for good. Only...Cole's not the only kid claiming to be Marcelo Araya-and one of them is telling the truth.

Can a real grandson, a fake grandson, a nosy neighbor girl, and the greatest mind ever to lose brain cells be a match for a top-secret, most ruthless organization? Ages 9-12.
