Isabella Marino believed numbers could always reveal the truth.
Then one hidden account destroys everything she thought she knew.
When millions vanish from the powerful Caruso crime family, the evidence points directly to Isabella's father. Branded a traitor and condemned to death, Lorenzo Marino has only days left before the underworld delivers its judgment.
Desperate to save him, Isabella makes an offer no one inside the council expects.
She will marry Roman Caruso-the cold, feared, and ruthlessly controlled underboss whose name makes powerful men lower their voices.
Roman does not believe in love. He believes in loyalty, leverage, and eliminating threats before they reach his door. To him, Isabella is the beautiful daughter of a suspected traitor, a dangerous weakness wrapped in an elegant dress, and the one woman capable of disrupting the control he has spent his life building.
Their marriage is supposed to be a contract.
Her father's life in exchange for her freedom.
But the moment Isabella enters Roman's heavily guarded estate, the danger becomes more personal. Threatening photographs appear inside locked rooms. Witnesses are silenced. Hidden passages reveal secrets buried for years. And every new piece of evidence connects their families to a mysterious criminal network known as Black Harbor.
As Isabella follows the trail her dead mother left behind, she uncovers forged signatures, stolen fortunes, and a conspiracy that began long before she offered herself to Roman. Someone has been watching her family for years. Someone predicted the marriage before it happened. And someone intends to use Isabella and Roman as the final keys to an empire built on blood, fear, and betrayal.
Forced to investigate together, the distrust between them begins to burn into something far more dangerous.
Roman becomes the man who shields her from bullets while questioning every secret she keeps.
Isabella becomes the woman who challenges his authority, sees the wounds beneath his brutality, and refuses to become smaller just to survive beside him.
But in a world where love creates leverage, their growing bond could destroy them both.
With her father's execution approaching, her brother hiding a devastating betrayal, and enemies closing in from inside the Caruso family, Isabella must decide how much truth she is willing to uncover-even if it ruins everyone she loves.
And Roman must choose whether to protect the empire he inherited... or the woman who has become the one weakness he can no longer deny.
Wed to the Ruthless Underboss is a dark, emotionally intense mafia marriage romance filled with forced proximity, dangerous family secrets, betrayal, suspense, protective obsession, and a powerful love story about two people fighting to choose each other in a world determined to use them.
When the vows were written in fear, only the truth can make them real.
Enter the dangerous world of Roman and Isabella-and discover what happens when a marriage arranged as a weapon becomes the one thing neither of them is willing to surrender.
