Selene was twenty-two years old when her life was traded like a business deal. On what was meant to be her birthday, she is instead handed an engagement ring and promised to the most feared man in the underworld, Tristan, the Mafia King. A man whose name commands silence, whose hands are stained with blood, and whose world has no room for love. Forced into a marriage she never chose, Selene walks down the aisle knowing one truth: this union is not about romance, but power. Their vows are not spoken before God, but sealed in blood, binding her to secrecy, loyalty, and a life surrounded by violence. What begins as fear turns into survival. In a world where betrayal is currency and mercy is weakness, Selene learns quickly that being Tristan’s wife makes her both protected and hunted. Every step she takes is watched. Every breath she draws belongs to a man who believes ownership is the same as devotion. But Selene is not fragile. As enemies circle, rivals plot, and old flames threaten her place, Selene begins to understand the rules of the mafia world, and how to bend them. The monster she married starts to change, not because he wants to, but because she refuses to break. Tristan has ruled through fear his entire life. Selene forces him to confront something far more dangerous: love. In a story of dark romance, forced marriage, obsession, power, and transformation, Vows Written in Blood follows a woman who was meant to be a pawn, and becomes a queen. Because in the end, the most dangerous thing in the mafia world isn’t the king. It’s the woman who survives him.
