She was forced into his mafia war. Now she fights it beside him.

The sins of the House of Diamanti have finally come due.

And Rome is burning.

Sabrina Badalamenti survived Sebastian's deceptions, his enemies, and the weight of his ring on her finger.

She is no longer leverage. No longer a pawn.

She is the one vulnerability he never accounted for.

Sebastian is the ruthless heir to an empire built on diamonds and blood—and now it is under siege.

His father is dead. The Judge is circling.

And the rot goes deeper than he ever suspected, straight into his own bloodline.

He has broken every rival who stood in his way.

But when Sabrina becomes the target, something far darker inside of him takes hold.

They came together as enemies.

They survived as reluctant allies.

Now, with betrayal closing in from every side, they must stand as one—or lose everything.

The Judge wants them destroyed.

His own blood may want worse.

And Sabrina is carrying a secret that will change the game entirely.

Some empires are built on diamonds.

Some are built on sacrifice.

Theirs will be built on the one thing neither of them planned for.

Betrayed Throne is the concluding novel in the Diamanti Billionaire Dynasty trilogy, featuring a dark, obsessive romance of war, betrayal, and the price of loyalty when love becomes the only thing worth protecting.
