Thomas Caine lives in the shadows. Betrayed and left for dead, he has put his past as a CIA assassin behind him. Now he lives off the grid, and hides from his dark past in the seedy underworld of Pattaya, Thailand.

But when local gangsters set him up for a crime he didn't commit, he finds himself back in the clutches of the CIA. His old masters make him an offer he can't refuse: rot in a hellish Thai prison, or accept a dangerous mission in Tokyo, Japan.

As he hunts the neon-lit city for a CIA asset's missing daughter, he quickly learns there is more to this assignment than meets the eye. Yakuza thugs, Japan's Security Bureau, and even rogue CIA operatives all stand between him and his objective.

And looming in the shadows is Tokyo Black, a right-wing terrorist cult whose members demonstrate their loyalty by burning their yakuza tattoos from their skin. Can Thomas Caine defeat this fanatical enemy, before they ignite an international conflict that kills thousands?
