A Geopolitical Thriller of Chaos for Profit

Tom Clancy meets John le Carré in an explosive chess match with nuclear stakes. The SENTRY Directive is a tense geopolitical thriller about spies, pilots, and the human cost of invisible wars.

When rising Indian diplomat Arvind Pratap Singh is assassinated in a Kabul bombing, a train is attacked in Pakistan's Balochistan province, and coordinated terror strikes hit Kashmir, the fragile India-Pakistan peace process collapses overnight.

Amid the escalating crisis, two unlikely figures are drawn into the shadows: Wing Commander Sohail Mirza (call sign Shadow), a decorated Pakistan Air Force pilot hardened by personal tragedy, and Ananya Rao, an Indian diplomat scarred by violence.

Evidence points to a covert network orchestrated by Darian Blackwood, a billionaire strategist whose Prometheus Group profits by engineering chaos and instability. Blackwood's mercenary enforcer, codenamed Ahab, executes the dirty work: assassinations, bombings, and disinformation campaigns designed to fracture alliances and keep India and Pakistan locked in perpetual hostility. The goal is not ideology but profit, turning chaos itself into currency.

From Islamabad to Geneva's back rooms, Shadow and Ananya pursue the truth through a labyrinth of betrayals. Shadow, haunted by the loss of loved ones to terror, struggles between loyalty to uniform and the moral clarity of exposing his own side's blind spots. Ananya, driven by duty but burdened by her fiancé's murder in Kabul, wrestles with whether cooperation with an enemy pilot is patriotism or betrayal.
