A traitor to humanity is helping a trio of alien races destroy humanity -- all of it. His motivations are unclear, his whereabouts unknown. But the traitor left something behind: a recording of his consciousness. That consciousness is poured into Jared Dirac, a warrior born as an adult to fight the battles no one else will take. As Jared fights, he learns more about the man whose personality has been placed in his head -- and learns why he turned traitor. But can Jared, bred to save humanity, be trusted not betray it instead?
