THE RUTHLESS VOW. (The Billionaire Sovereign Dominion: Book Three) - Excel Samuel

They survived assassins, syndicates, and betrayal. But they didn't survive each other.

The Syndicate is ash. The Leviathan Code is deleted. The empire is standing.

Elena and Kaelen won.

So why does she feel like a prisoner?

Three weeks after the fires in Austria, the Dominion is impenetrable and suffocating. Kaelen Vance, the man who once called her his equal, has quietly, methodically locked every door. Revoked her access. Grounded her flights. Surrounded her father with armed guards. He tells himself it's protection. Elena knows the difference between a shield and a cage.

But before she can fight the war inside their walls, the Syndicate launches their most terrifying weapon yet, one that can't be shot, hacked, or burned.

A federal warrant. With her name on it.

Interpol. The NSA. The full weight of international law was all weaponized by the Syndicate's buried political assets to frame Elena and her father as global cyber-terrorists. No mercenaries. No malware. Just paper. And paper doesn't care about titanium walls or sovereign airspace.

Kaelen has thirty days to dismantle a legal conspiracy buried inside the world's most powerful governments before his empire is sanctioned, his assets are frozen, and Elena is dragged out of his fortress in handcuffs.

But Elena Rossi didn't survive ten years of ghosts and a billionaire's obsession to sit behind reinforced glass and wait.

She has a plan of her own.

And the King just forgot that he taught her how to disappear.

The Ruthless Vow is the explosive third chapter in the Billionaire Sovereign Dominion series - where the enemy wears a suit, the battlefield is a courtroom, and the most dangerous move on the board isn't a bullet.

It's a Queen going rogue.
