The SENTRY Directive Two broken souls from enemy nations. One phantom mercenary. A countdown to nuclear winter. One bomb in Kabul stripped Indian diplomat Ananya Rao of everything she loved. Across the border, a synchronized train explosion in Pakistan tore apart fighter pilot Sohail Mirza's (callsign: Shadow) family. Years later, a wave of catastrophic terror strikes pushes India and Pakistan to the absolute brink of annihilation. Hunting the ashes, Ananya and Shadow discover they are chasing the same ghost: Ahab, a surgically remade mercenary whose brutal signature marks every attack. But Ahab is merely the weapon. Behind him stands Darian Blackwood, a cold-blooded corporate strategist who orchestrates global chaos for profit. Forced into a fragile, high-stakes alliance, the diplomat and the pilot must survive deadly summits from Geneva to Istanbul. Together, they race to build SENTRY-a multinational task force designed to break the cycle of terror before the weaponization of shared rivers ignites the region. But as the fuse burns down, they discover the ultimate threat isn't marching across the border. It's already inside the room. Whom do you trust when the enemy wears a tailored suit and a smile? If you love the blistering pace of Tom Clancy, the complex espionage of Vince Flynn, and high-stakes regional geopolitics, you won't be able to put down the first book in Shakil R.'s explosive new series.
