Shepherd's Watch. Onyx Tactical, #1

She created a cure. They turned it into a weapon. Now, she's the only evidence left. Dr. Amy Hendren spent eight years developing a breakthrough gene therapy. But when she discovers her corporate employers have twisted her work into Project Chimera-a biological kill switch-she does the only thing she can. She steals the data and runs. But you can't hide from a multi-billion-dollar giant with the world's most ruthless security firm, Acheron, on its payroll.
He's a ghost living on the failures of his past. Jack "Shepherd" Wolfe and his team at Onyx Tactical exist in the shadows. Disgraced and discarded after a deadly betrayal in Syria, they take the jobs no one else will. When a terrified scientist calls their untraceable number, Jack sees her as just another asset to protect. But Amy is different. She's brave, defiant, and possesses a mind that sees the world in physics-mass, momentum, and the devastating velocity of the truth.
The hunt is personal. The stakes are terminal. As Acheron closes in, Jack realizes the man pulling the strings is the same monster who left his original team for dead. To save Amy, Jack must lower his walls and trust the woman who is systematically breaking through them. In a world of deepfakes and corporate lies, the deadliest threat is the one you let get too close. SHEPHERD'S WATCH is a full-length, high-stakes military romantic suspense.
It features an ultra-protective hero, a genius heroine who holds her own, and a found-family team of elite operators. Come for the heart-pounding action; stay for the scorching slow-burn. Heat: 3/5. No cheating, no cliffhangers, and a guaranteed HEA.
