Colonel Steven Scott agreed to die for one of America's most closely guarded experiments.
He did. And then came back.
Now foreign intelligence wants PSYCHONIX, someone inside the program has betrayed it-and the only man who knows what the technology can truly do is carrying it inside his skull. A former Green Beret, combat-wounded and still fighting the hidden war that followed him home, Scott has survived men who wanted him dead before.
This is different.
Created by his stepbrother, brilliant neurosurgeon Dr. Mark Starr, PSYCHONIX-Psychological Bionics-is a revolutionary neural-noetic interface designed to augment the brain, but it opened a door between realities. To prove PSYCHONIX could cross that bridge, Scott had to die. His heart stopped. His body stayed behind. And for four minutes and thirty-eight seconds, his conscious mind crossed a threshold no soldier, scientist, or intelligence service had ever been able to reach.
Then he came back.
Remembering a realm his body never entered.
The CIA is watching. Foreign intelligence is closing in. They know PSYCHONIX can do more than enhance a man's brain. It will change the balance of power, and Steven Scott is the key. If they can't steal the secret from the laboratory, they'll come for the only man carrying it.
Scott has one advantage.
They've never fought a man who has already been dead.
Surviving what comes next is the mission.
The first arms race for access to the human soul has already begun.
