He’s a devil in holy robes . . . and I’m trapped inside with him. 

Katarina: My mother pulled strings to get me into Hallow Hall Institute—a place for the lost, broken, and damned. She said I was lucky, blessed. Here, doctors would mend my mind, while priests and nuns saved my soul. They say the voices I hear aren’t real, just delusions. But despite the holy men, evil lurks in the shadows. I feel it. I see it. And then—he arrives. Handsome. Charming. A wolf in devotion, with scripture on his lips and sin in his eyes. Within days, he has them all under his spell. But when he looks at me… I know. The devil himself has come to Hallow Hall. 

Massimo: My life is built on blood and vengeance. I kill for money. I live for retribution. My work leads me to Hallow Hall—a place of whispers and suffering, where faith is a mask and monsters wear crosses. To get close to the man who needs to die, I put on the robes of the righteous. And then I see her. The girl who speaks to angels. The girl who sees right through me. She calls me a devil. She’s right. And I’m going to drag her into hell with me.
Book 2
An ex-special forces mafia underboss. The woman who broke his heart. And an arranged marriage that could destroy them both . . . A fiery enemies-to-lovers romance from the author of Unholy Vows

She’s not my wife . . . she’s my hostage.

Fourteen years ago, Georgia Bellisario ripped my heart out and left me for dead.

I should have died that day. Maybe I did.

The man I was—the one who loved, who felt—was buried in the dirt.

What remained was a body, a machine built for war and violence.

I was reforged in blood, remade into something ruthless.

Now, I am the sottocapo of a brutal mafia, the perfect weapon at my boss’s command.

Merciless. Heartless. Remorseless.

When the boss orders me to hunt down Georgia and drag her back across the country, I don’t hesitate.

Her name alone is a curse, a toxin that burns through my veins.

She’s still my obsession, my weakness—the poison that never left my system.

I was the perfect weapon, until my boss announces her engagement—to another man.

That’s when I decide: If Georgia Bellisario is destined for a wedding… it will be to me.
