A man with no identity...hunting a man without limits.

When a pile of bodies is found in Paris, CIA Agent Tom Blake hustles his way onto a major case: tracking a man with enhanced abilities, the test subject of a secret government program.

There's just one problem: the man using Agent Blake's identity is not Agent Blake. He's Tom Reese, a man without a family or a home.

Reese is searching for his brother's killer. He stole Agent Blake's identity two months ago and has bluffed his way onto the team investigating his only lead. But his time as a CIA agent is accelerating toward its expiration date.

Soon the CIA will find out that Agent Blake is in two places at once. Soon the augmented man will come looking for him. And soon both will discover that Tom Reese carries a secret even he doesn't know about.

He is the last test subject of Project Prometheus.
