Serene/Serenity Verena Devone, known in the underworld as Agent White, is a top-tier weapon forged for one purpose: the perfect kill. Her current mission is her most dangerous yet-infiltrating the inner sanctum of the world's most wanted and powerful man, Zayne Damien Del Montevard Li. She will disguised as the quiet, unassuming Savannah Gray, she has successfully secured the position of his personal assistant. Her goal is simple: gain his trust, gather intelligence, and dismantle his multi-billion dollar mafia empire from the inside. Zayne is a man of shadows, a lethal kingpin who trusts no one and commands with a heart of ice. But as Serene moves deeper into his private world, the mission becomes a psychological battlefield. Every move is a gamble, and every secret she uncovers leads to a haunting question: Is Zayne really the heartless criminal she was trained to destroy, or is there a different truth hidden behind his cold gaze? As the stakes rise and the Agency demands blood, the lines between the cold-hearted agent and the shy assistant begin to bleed together. Will she succeed in her mission to bring him down? Or will the mask of Savannah eventually take over Serene?
