The O’Sullivan Empire Series – Box Set Volume 1

Books 1–3: Callum • Rory • Niall

Power is inherited. Loyalty is enforced. Love is dangerous.

Welcome to the O’Sullivan Empire, where blood builds empires and mercy gets you killed. The O’Sullivan brothers rule the Irish underworld with iron fists, unbreakable loyalty, and a willingness to burn the world for what’s theirs.

CALLUM
The leader. Cold, calculating, and relentless. Callum O’Sullivan doesn’t fall in love—he claims. Once he decides a woman belongs to him, there is no escape from his protection… or his control.

RORY
The wild one. Charming, reckless, and lethal. Rory lives fast and fights dirty. But when desire turns into obsession, he’ll destroy anyone who threatens what he refuses to lose.

NIALL
The enforcer. Silent. Deadly. Devoted. Niall speaks with action, not words. Touch what’s his, and you won’t get a warning—only consequences.

Together, the O’Sullivan brothers run an empire built on blood, family, and absolute power. Betrayal is paid in violence. Love is possession. And once you’re pulled into their world, there is no way out.
