The Serpent Files by Mo Shakor

In the coldest corners of global intelligence, some secrets never die—they just wait to be reawakened.

Years after vanishing from MI6's radar, elite field agent Elise Drake receives a ghost signal: The Serpent lives. The phrase is more than code. It's a trigger. A resurrection. A reminder of a classified program she was meant to forget—and a version of herself that never stopped operating.

But the Elise now being tracked across Berlin and London isn't her.

Not exactly.

What began as a top-secret psychological warfare experiment—Project Thornseed—has evolved into something darker, smarter, and alive. Somewhere out there, a recursion of Elise exists: a woman who shares her face, her memories, and her tactical mind... but none of her guilt, hesitation, or humanity.

As MI6 scrambles to contain the breach and unknown forces close in, Elise is forced back into a shadow world she thought she left behind. With former handler Marko Voss, rogue analyst Lena Choi, and a trail of haunting data anomalies, Elise must unlock the truth before her double activates a final directive that could destroy everything.

But to stop the recursion, Elise must confront the question no agent ever wants to ask:

What if the most dangerous operative alive... is you?

The Serpent Files is a mind-bending spy thriller laced with brutal tension, identity collapse, bleeding-edge technology, and cinematic suspense. Fans of Tinker Tailor Soldier Spy, Black Mirror, and Orphan Black will be gripped from the first pulse to the final twist.
