The Mafia Heir’s Obsession by Kristen Luciani

He was never supposed to touch her. Now he’ll burn the world to keep her.
Callahan Murphy is a ruthless Irish mafia boss with blood on his hands and vengeance in his veins. When he strikes a power deal with a New York crime family, marriage to the Don’s daughter is just another strategic move—until everything goes to hell.

Because the bride he’s promised? Vanishes. And her younger sister is offered in her place.
Lucia de Rosa is untouched, unwilling, and unprepared for the savage man who now claims her as his own. She thought this arrangement was temporary—a mistake that could be undone once her sister returned.
She was wrong.
When a violent night in Queens ends with her pinned beneath Callahan, gasping for breath and drowning in pleasure, she realizes her life will never be the same. He’s her father’s ally, her family’s nightmare, and her most dangerous mistake.

But Lucia isn’t the submissive bride Callahan expected. She fights him at every turn, challenging his authority and igniting a possessive hunger that threatens to consume them both. Every moment of defiance makes him want her more. Every touch makes her crave the very man she should fear.
He swore he’d never let her go. But when family secrets unravel and blood debts come due, their arranged marriage becomes a battlefield where love and loyalty collide.
In his world, she’s not just a woman—she’s a weapon, a weakness, a wife. And he’ll kill anyone who touches her.

But when enemies close in and the past refuses to stay buried, Callahan will have to choose: protect his empire or save the woman who’s become his everything.
Obsessive. Possessive. Unforgiving. Some marriages are made in heaven. Theirs was forged in blood.
