The O'Sullivan Empire Series

Callum

CALLUM is Book 1 in the O’Sullivan Empire Irish Mafia series, a dark romance where devotion is dangerous and love comes with a body count.

Callum O’Sullivan does not fall in love. He calculates, he controls, and he wins. As the heir to an Irish empire built on blood and power, he has spent his life protecting his family name at any cost. Emotions are liabilities. Softness gets you killed. Then Savanna crashes into his world like a match to gasoline, all sharp mouth and hidden bruises, carrying trouble she refuses to name.

Savanna has spent years surviving by staying two steps ahead of everyone who has ever tried to own her. She does not need a savior, and she definitely does not need an Irish mafia prince with a cold stare and a possessive streak a mile wide. But when the past comes hunting and nowhere feels safe, Callum offers her a choice: stay under his protection or be left to the wolves. It is a deal she never wanted to make… until she realizes his protection feels a lot like claiming.

What starts as a guarded arrangement turns into obsession, and obsession turns into war. Because in the O’Sullivan world, loving the wrong woman is not a weakness. It is an invitation. And Callum will burn down anyone who thinks they can take what is his.

Inside Callum, you can expect:

• Irish mafia heir with touch-her-and-die devotion

• Forced proximity and protective obsession

• A fierce heroine with secrets and bite

• High stakes danger, loyalty, and vengeance

• A dark, emotional romance with a hard-won HEA
