The Extraction Protocol

She taught people how to disappear. She never thought it would be used against her. Dr. Lena Voss left the Agency's covert extraction program in disgrace. She traded aliases for a small-town practice. She built a quiet life from the wreckage — one without ghosts, without handlers, without the cold mathematics of who survives and who doesn't. Then a rainy Tuesday dissolved everything. Her thirteen-year-old's bedroom: empty. A burner phone on the pillow. A voice she had been certain was dead on the line. Kessler. The rogue intelligence broker who torched her career five years ago, then died in a very public, very bloody car bombing in Zurich. He is not dead. He has her daughter. And he wants Lena to assemble her most dangerous former colleagues to steal a biotech prototype from a black-site laboratory in the Baltic Sea — a floating fortress with rotating security, biometric locks, and a failsafe designed to incinerate everything the moment an alarm trips. Seventy-two hours. An impossible job. A team she does not trust. Because someone inside that handpicked crew is feeding Kessler real-time intelligence. Every move Lena makes tightens the noose around her daughter's neck. And the one person who might have helped her — the handler who once loved her — is now the lead investigator hunting Lena for a murder she did not commit. The deeper she drills into the lab's secrets, the clearer it becomes: the prototype isn't a weapon or a cure. It's a key. A key to a conspiracy that reaches the highest corridors of power, and Kessler is only the frontman for people who will erase entire bloodlines to keep it buried. Lena built her career on making people vanish. Now she has to weaponize that skill in a way no one — not Kessler, not her betrayer, not the people pulling every string — sees coming. The Extraction Protocol is a fierce, claustrophobic psychological thriller about a disgraced operative, a stolen daughter, a heist with no margin for error, and the kind of betrayal that only a person who knows you completely can execute. Perfect for readers who love twist ending thrillers, morally complex heroines, spy-craft suspense, high-stakes infiltration, and fans of Seraphina Nova Glass and Megan Lally. A relentless, twist-packed standalone thriller.
