The enemy is relentless, but they made one fatal 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' 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 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. Line of Fire is the first book in the Christian thriller series Dauntless Defenders. It is NOT a standalone novel.

The enemy believes the battle is nearly over, but he’s just getting started. Sector 17 has tried to silence the Ghost of Oz, but he doesn’t back down. Back on the hunt, Tyler Reid uncovers chilling truths that challenge everything he knows about his enemy and the woman who works for them. Caught between protecting a Russian heiress and the job she has to do, Tyler starts to question who he can rely on. Alexandra “Alex” Romanova has been told who she is, but fragmented memories hint at a past she's reluctant to reclaim—a past far darker than what she remembers. When Tyler offers her a chance to escape her cruel boss at Sector 17, the plight of young recruits being turned into killers weighs heavily on her conscience. She’s determined to give them the same freedom she's found, but doesn’t realize that in doing so she has put them all at risk. As the head of Sector 17 clings to power, Tyler and Alex are caught in the middle of a deadly war for lives, freedom, and revenge. With enemies closing in on all sides, they can't save everyone. The stakes are higher than ever—there is no time to die.

He’s left the past where it belongs. But then it comes knocking at his door. The silence following Tyler Reid's last mission has him eager for the next job. So when a woman from his past shows up on his doorstep with a new task—extracting a kidnapped Indian doctor from rival mercenaries—he’s ready to move. It’s dangerous. It’s fast-moving. It’s exactly what he wants. The only problem is Alexandra Romanova is going too—the one person who sees the cracks in his armor he's trying to hide. Alexandra “Alex” Romanova has returned to Russia, but she’s not ready to step into her father’s legacy. So she seizes the chance to delay that future. Especially when she learns who’s missing—and who’s going after him. But working alongside Tyler again tests more than her training. He’s different. More guarded. And something in him is unraveling. From Libya to India to Morocco, the team races to find the missing doctor while avoiding the trap the enemy has set. But every step closer to the truth puts more pressure on the cracks already forming. And as the mission begins to spiral, Alex realizes the real danger may not be the enemies chasing them—but the severed ties Tyler leaves behind when he decides the mission is over.
