Mademoiselle alliance. Natasha Lester. 2025.

How did a young Parisian mother, celebrated for her beauty and glamour, come to lead the largest spy network in France?

Morocco, 1928.

Eighteen-year-old Frenchwoman Marie-Madeleine is not the kind of woman who goes through life sitting down, something her new husband can attest. Her unconventionalities - rally car driving, flying planes and dabbling in intelligence work for the government - earn her a reputation, but she knows who she is at heart: an adventurer.

Paris, 1936.

Europe teeters on the brink of war, a chance encounter with a mysterious man codenamed Navarre turns Marie-Madeleine’s life upside down. Recruited to help build a resistance network known only as Alliance, she conceals her identity - and her gender - as she navigates a perilous double life away from her children and the man she loves. Capture and death are only a heartbeat away.
