The enemy is relentless, but they made one fatal mistake: they underestimated him.

Australian mercenary Tyler Reid, known as "The Ghost of OZ," has a talent for evading detection, a skill that has caught the eye of multiple government agencies. When a shadowy group targets a CIA asset and her revolutionary drug ND1, the Deputy Director calls in Tyler. Eager for action, Tyler takes the job. He soon realizes that the enemy is not only after the drug, but also out for his blood. Then the mission goes south, and he is forced to seek an unlikely ally.

For covert foreign operative Alexandra Romanova, freedom is a distant dream. Escaping one prison only led her to a more dangerous one. Her deadly skills are at her boss's disposal, but she'll use them only to escape. Her final chance hinges on retrieving ND1, but the elusive Ghost of Oz complicates things. Tyler Reid isn't an easy mark, and the better she gets to know him, the more she questions the mission she's tasked with. Soon she faces a dire choice: kill a man she is convinced is good, or pay with her own life.

As Tyler and Alex venture beyond their orders, the line between enemy and ally blurs. On the edge of failure, trust becomes a dangerous gamble with every decision dragging them deeper into the line of fire. As enemies close in and alliances shift, they are ensnared in a ruthless battle where survival depends on split-second choices. In this high-stakes fight, time is running out, and the margin for error is zero.
