Mob princess Brianna O'Reiley has just discovered she is pregnant. What should be a joyous occasion is actually a nightmare because she knows that the father is not the husband she recently lost in a mob ordered murder, but Alessandro Dardano, the son of mob boss Bernardo Dardano, her family's greatest enemy. Brianna and Alessandro shared one night of passion after taking shelter in a snow storm, neither knowing the other's identity, that they were the children of families who have had a blood soaked vendetta between them for the past fifty years. Alessandro Dardano, has returned to New York from running his father’s business overseas to take his place as Bernardo’s successor. The passion he and Brianna generate between them make him question his loyalty to his father, but even more, the love he feels for her makes him want to do whatever he must to make Brianna his, despite her last name. Brianna, who has vowed to make Bernardo pay for his part in her husband's murder, is torn between the searing love she feels for Alessandro and her desire for vengeance. Will this baby bring the two families together, or will he be the lit fuse in an explosion of violence that destroys both sides forever?

Brianna and Alessandro are in Ireland to uncover the truth about the love between their ancestors Francesca and Adriano, a love that is at the center of a vendetta that has raged between rival mob families the Dardano's and O'Reiley's for over fifty years. When they return to New York, it is with the certainty that the only way to end the vendetta is to bring their two families together. Brianna and Alessandro marry, determined that their love will flourish despite the animosity that still reigns between their families. But it quickly becomes evident that neither branch of the O'Reiley and Dardano family is willing to accept this attempt to end the vendetta. Brianna and Alessandro find their loyalties more divided than ever before as those they love conspire around them, leading to a shocking betrayal that could destroy their love forever. And still, the violent specter of Arturo Dardano, the younger Dardano brother, determined to seize power away from his brother, remains.

Brianna and Alessandro's marriage is in ruins. After allowing their families to corrupt their love for each other with lies and heartbreaking betrayals, they are farther apart than ever. Yet the love between them refuses to relinquish its hold. When Arturo's evil threatens their children, Brianna and Alessandro put a plan in motion and escape to Italy where they make their way back to each other. Just as they have reaffirmed their commitment to their love, a shocking discovery is made that will cause the O'Reileys and Dardanos to put aside their legacy of hatred and violence and come together to fight Arturo's psychotic thirst for power in a final showdown that will change both families forever.
