One agent. One mission. One truth she was never meant to uncover.
Fiona Laval was once one of the Special Operations Executive’s most daring agents—brilliant, unpredictable, and willing to walk into the jaws of the German war machine with nothing but a knife, a radio, and her own ferocious will. But France cost her more than London will ever know, and the aftermath has left her broken, drinking herself numb in the remote exile known only as The Cooler.
Trevor Jones, the man who trained her—and failed to protect her—refuses to let her disappear. Spiriting her away under false pretences, he begins a dangerous gamble: saving Fiona from the ghosts that stalk her dreams… and from the bottle that promises oblivion. But as withdrawal, guilt, and the spectre of her past close in, Fiona learns the truth: she is needed again.
Because deep in occupied France, a legendary resistance leader known as Martingale—a man who trusts no one—is facing betrayal, collapse, and the threat of German reprisals that could cripple the Allied invasion. And Fiona Laval may be the only person he would ever believe because he is her father.
With D‑Day looming and London desperate, Fiona must choose: confront the trauma she’s been running from, or let a mission that could change the course of the war burn to ash.
In a world where loyalty is fragile and survival is never guaranteed, Fiona must prove not only that she can return to the field—but that she deserves to.
Heart‑pounding, emotionally charged, and rich with the shadows and secrets of WWII espionage, Martingale is a story of redemption, betrayal, and the haunting cost of courage.
