Nadia Sinh is a born-and-raised Citadel agent. Her mother was Citadel so it seemed only right that Nadia would follow in her mother’s secretive footsteps. Next to Mason Kane, Nadia is one of Citadel’s most fearless Tier-One agents. She possesses an indefatigable strength and passion for fighting for what’s right and good in the world. Nadia meets Mason Kane for the first time while on mission in the Alborz Mountains. From the moment they lock eyes, their attraction to one another feels fated. Despite their high stakes job as spies for the world’s most powerful intelligence agency, the two grow to love one another. And more than anyone else in the world possibly could, they actually get one another. But sometimes mutual understanding isn’t enough to maintain stability, however much it might be underpinned by love. Just before the fall of Citadel, we learn that Nadia and Mason’s relationship was in ruins. The cutthroat world of espionage and the endlessly compulsive need for secrecy above all else finally brought their romance to the edge. Before we can learn what happened in their relationship, Manticore stages their global attack on Citadel, leaving Nadia and Mason fighting for their lives.
