Some rivalries are born from ambition. Theirs was carved in blood, betrayal, and vengeance. For centuries, the Rawals and Vardhans have waged war-on the streets, in the boardrooms, in politics, and behind closed doors. It was never just about power. It was personal. Zaisha Rawal was born into fire, raised to be ruthless. The woman men fear but desire, a queen who doesn't need a throne to command. She rules the underworld of business, outmaneuvers politicians, and leaves her enemies with nothing but regrets. Ahanveer Vardhan is the storm she was warned about. A name that demands loyalty and feeds on fear. A man who doesn't forgive, doesn't forget. A criminal in shadows, a king in daylight, a nightmare in flesh. They were never meant to co-exist. Yet, they do. And that is the problem. They don't just ruin each other's deals. They burn each other's empires to the ground. They don't just trade threats. They play games where the loser pays in blood. They were never meant to be anything but enemies. Until one night. One moment. One irreversible mistake. She walks down the aisle like a queen heading to war. He waits for her at the altar, like he owns her soul.... The world calls it a union. They know it's something deadlier. Because whatever forced them into this marriage is dangerous enough to make even Zaisha and Ahanveer bow to it. But they are not lovers. They are not partners. Because hatred has always been their foundation. Now, but it's turning into something worse. Something twisted. Something obsessive. Something they cannot control. They could destroy the world to win against each other. But what happens when they start craving the very thing that could destroy them? Because in this war, love isn't just forbidden. It's the deadliest sin.
