The Demon’s Vow

This audiobook is narrated by a digital voice.

Leon is not a man who can be saved. He is a man who destroys.

Feared in the criminal underworld, Leon built his empire on blood, violence, and chaos. Killing is not a necessity—it's his nature. When his brother is brutally murdered, the last fragile line keeping him tethered to reason snaps. Vengeance becomes his religion, and he is willing to commit the ultimate sin to achieve it.

His target?

The Bonanno family.

Leon infiltrates their world by making a vow he never intends to honor: marriage to Mady, the sheltered, golden-hearted 'princess' of the mafia. To her, Leon is dark, intense, irresistible—the man she believes is her forever. To him, she is a weapon. A means to annihilate everything her family holds sacred.

But revenge has consequences.

When Leon abandons Mady at the altar and exposes his cruel deception, he leaves behind more than shattered dreams. Bound by betrayal, secrets, and an unforgivable truth growing inside her, Mady must survive the aftermath of loving a monster. And Leon? He doesn't regret a thing.

Because demons don't feel remorse.

They only keep their vows—to destruction.
