Safely ensconced in his jungle hideaway, Solo uplinks to the satellite network that circles the globe and discovers an amazing fact. He's not alone. There's another one like him. Code-named Nimrod, it has the same extraordinary physical and computer-reasoning abilities as Solo. In all senses but the biological, the two are brothers, bound by a tie, they share with no other creature on earth.

Determined not to repeat the mistakes they made with Solo and its humanistic education, the Army is conditioning Nimrod with electronically induced pain reinforcement. in fact, they've created a monster. Instead of the unquestioningly obedient robot it appears to be, Nimrod is a brilliant paranoid, with no moral core and the strength of thirty men.

As Solo strategizes his assault, Nimrod quietly begins to discover its power, and to plot its own violent revenge. The stage is set for the ultimate confrontation, one that will keep readers on the edge of their seats and once again establish Robert Mason as a unique master of high-tech adventure.
