When India and the CIA return to Nanda Devi for a second high-risk operation, undercover operative Zaif is thrust into a world of silent ridges, coded transmissions, and rivals hidden in the snow. As danger closes in from all sides, Zaif must rely on instinct, grit, and raw survival to navigate a mission where nothing is as it seems. A gripping 1970s espionage thriller-tense, atmospheric, and unrelenting.
