American traitor / Brad Taylor.

An enemy is dangerous. A traitor is lethal. They call them the Taskforce. Designed to operate outside the bounds of law, trained to exist on the ragged edge of human capability, their existence is as essential as it is illegal. Recruited from top operators in the intelligence spheres and led by ex-Special Forces Operator Pike Logan, they're a formidable unit. Prepared for anything. And they need to be. Whilst aiding an ex-Taskforce member on the run from Chinese agents, Logan uncovers a plan to bait Taiwan into all-out war by destabilizing their government and manipulating their artificial intelligence controlled defence system. With the threat of conflict reaching boiling point, Logan alone realises that all is not what it seems. For a man used to confronting his enemy in close-quarters combat, he faces a dilemma: how do you defeat an enemy that you can't see?
