His Vow, Their Sin

I thought I was sacrificing my future to save my family.I was wrong.When the Bellini empire begins to crumble beneath betrayal, debt, and blood, I'm offered a single way to keep my father's legacy alive—a marriage to Alessio DeLuca, the cold, calculating heir to one of the most powerful mafia dynasties in America.On paper, it's a business arrangement.A vow.A contract.A price I'm willing to pay.What no one tells me is that nothing inside the DeLuca empire belongs to one man alone.Not power.Not loyalty.And certainly not me.Alessio rules with discipline and impossible control. Dante, the family's ruthless enforcer, seems determined to make me regret every breath I take. Francesco smiles like temptation itself, pulling me into dangerous games where every secret has a cost.Three kings.One bride.No escape.Every lesson they teach me blurs the line between protection and possession until I no longer know where fear ends and desire begins. The deeper I'm drawn into their world of blood-soaked loyalty and ruthless ambition, the more I realize the greatest threat isn't the enemies outside the family.It's becoming one of them.Because survival demands more than obedience.It demands transformation.They thought they were claiming a bride.They never expected to create a queen.His Vow, Their Sin is a scorching dark mafia reverse harem romance featuring possessive antiheroes, a marriage of convenience, dangerous obsession, political intrigue, morally gray characters, and a heroine who discovers that the greatest power belongs to the one everyone underestimates.This novel contains explicit sexual content, violence, coercive relationship dynamics, and mature themes intended for adult readers (18+).
