This book picks up from The Code Beneath Her Skin, Book 1 in the Shadow Files thrillers
Olympic gymnastics champion Jewel Carlone has the world at her fingertips—until a routine performance in Paris ends with armed men, a chemical-soaked cloth, and darkness. She wakes imprisoned in a fortress hidden in the Atlas Mountains, a pawn in a terrifying game she doesn't understand.
The target isn't Jewel—it's her fiancé, Dr. Leal Trelles, whose revolutionary fertility research has been stolen and weaponized by a brilliant geneticist with a god complex. Dr. Zain Kahale believes he's saving humanity from extinction through forced genetic "correction." His weapon: a compound that can selectively sterilize entire populations, deployed through legitimate pharmaceutical channels. His leverage: the woman Leal would sacrifice everything to save.
But Kahale underestimated his captive.
Jewel isn't waiting for rescue. Using the discipline that made her a champion and the intelligence that made her survive, she transforms from victim to strategist to warrior—leading scientists, defying guards, and planning an escape that will take them through burning facilities and impossible odds. Meanwhile, Leal assembles an unlikely team—a fierce human rights lawyer, a moral-compass scientist, a cyber-forensics genius, and a DEI agent who might be their only government ally—to stop deployment of a eugenic program that threatens millions.
From Moroccan compounds to Maltese warehouses to Austrian fortresses, they'll race against a 72-hour countdown, face impossible choices between love and humanity, and discover that stopping a villain who believes he's a savior might require becoming something they never imagined.
When the world needs saving, can an Olympic champion and a dedicated scientist become the heroes millions will never know they need?
Perfect for fans of A.G. Riddle, Matthew Mather, and Karin Slaughter—with the heart of Nora Roberts and the science of Michael Crichton.
“Rocket-fuel pacing with a heroine I’d follow into fire. This thriller moves.”
“Ethical dread and big-hearted romance in one breathless, globe-spanning ride.”
“I came for the science hook, stayed for Jewel’s transformation and the found-family team.”
“The villain’s ‘I’m saving you’ logic is chillingly believable—couldn’t look away.”
“Cinematic set pieces, smart twists, and a final act that left me fist-pumping.”

Rose Sandy is the author of the high-stakes Shadow Files thrillers — smart, global espionage stories where brilliant women go up against tech giants, covert agencies, and ruthless power brokers. Drawing on her background in international publishing and her fascination with how information is controlled, Rose writes twisty, technology-laced thrillers that move from boardrooms to deep-sea labs to palaces and private islands, always with a woman at the centre who won’t be intimidated.
Her heroines — cyber-ops specialists, oceanographers, investigative analysts, intelligence insiders — don’t wait to be rescued; they outthink, out-hack, and out-run the people trying to silence them. In the Shadow Files world, secrets have a price, science can be weaponised, and the most dangerous thing in the room is an intelligent woman with proof.
When she isn’t plotting international conspiracies on the page, Rose Sandy is championing diverse, female-forward storytelling through Silver Gravity Entertainment, helping other writers bring bold, global stories to readers.
Where imagination knows no bounds and adventure awaits at every turn.
