Blood-bound vows

They've hated each other for years-long before they ever stood in the same room.

Their rivalry was built through crossed paths, failed operations, whispered reputations, and the destruction they left in each other's wake. Every encounter ended with another reason to hate the other.

So when Lucía Cárdenas attends her best friend Camilla Delgado's wedding, she's prepared to celebrate-not to come face to face with the one man she's spent years wanting dead.

Leon Montanari.

Forced into the world of one of the most powerful mafia families, old wounds are ripped open. What begins as cold politeness quickly descends into sharp insults, dangerous games, and a battle for control neither of them is willing to lose. Every conversation becomes a challenge. Every glance feels like a threat.

Then everything changes.

When a ruthless enemy organisation emerges and sets its sights on the Montanari family, Lucía is pulled into their world and placed under the family's protection. Trapped inside the Montanari manor, she's forced into constant proximity with the man she despises most.

With enemies closing in from every direction, survival demands an alliance neither of them wants to make. Trust is earned through blood, impossible choices, and battles that blur the line between hatred and loyalty.

Because in a world ruled by violence, power, and control, the most dangerous thing isn't falling in love with your enemy.

It's discovering they may be the only person capable of destroying-or saving-you.
