Rate this book
He destroyed me and called it protection. Now I need him, and he knows it.

Gemma
I swore I'd never come back to this city. I swore I'd never say his name again.
Then someone murdered my brother, and every answer leads back to the world I escaped.
And the one man I can't forgive—Alessio Ferraro.
He’s the man who threw me away like I was nothing.
Now he's powerful, feared, and he’s built a kingdom out of vengeance.
He has conditions for helping me.
Stay close. Follow his rules. Don't ask about the past.
I still hate him. I still yearn for him.
He says he let me go to protect me.
I say he destroyed me and called it mercy.
The truth? It might be both.

Unholy Union is a spicy dark mafia enemies-to-lovers romance with a second chance that cuts deep, a vengeful hero, and the kind of reunion that leaves scars.

Unholy Union by Kendall Jacobs was an addictive dark mafia romance that kept me hooked from beginning to end. Kendall did a great job combining danger, intense chemistry, suspense, and plenty of steamy moments. I enjoyed the darker atmosphere and the morally gray characters, which made the story feel exciting and unpredictable. The romance had plenty of tension and emotional twists, while the mafia element added higher stakes and kept me wondering what would happen next. The characters had their flaws, but that made them more interesting and fit perfectly with the darker tone of the story. Overall, Unholy Union was a fun addition to the Empire of Sinners series!
