**BLSC #8 - HER BLACK KNIGHT** Marco Hastington presents himself as an emotionless corporate titan—calculated, detached, and consumed by his empire. Romance has never crossed his radar until a fateful encounter with a woman carrying secrets far darker than his own. Her piercing blue gaze locks onto his, igniting something he never knew existed within his carefully constructed walls. Cassandra Lancio exists in chains invisible to the world. Bound by her parents' mounting debts, she serves as a lethal instrument in the hands of Patt Brooks, one of the underworld's most ruthless kingpins. Forced to manipulate her way into the life of a man named Lincon, her carefully orchestrated plan shatters when she collides with Marco instead—a complication that neither of them saw coming. "Get off me! Mind your own business, Marco Hastington. Don't make me shoot you instead," she snaps, her voice cutting through the tension like a blade. What begins as a collision between a desperate woman and a man who knows nothing of desperation becomes something neither anticipated. When Marco discovers the chains binding Cassandra, his cold exterior cracks. In a world where survival means betrayal, their contract may be the only truth either of them can trust.
