Royal Blood by Claire C. Riley

When duty & jealousy collide, the flames of temptation are fanned

Natalia has always known that she was promised to a man 25 years her senior. However, after the Novello brothers, come to the aid of her father, feared mafia Don Frank Costello, everything changes.
He’s king of the underworld. The Don of NYC. He has money, drugs, guns, thriving businesses and half the police force under his belt. So when he offers the brothers payment for helping him, he’s surprised when the only thing they demand is Natalia.
Unable to refuse their offer, Frank reluctantly hands over his only daughter to the Novello brothers and a war breaks out between the three families.
When duty and jealousy collide, the flames of temptation are fanned and the only thing standing in the way of bloodshed and war is the promise of seduction from the only daughter of Frank Costello.
Can there ever be life after the Brotherhood take their payment from her? Or does the ultimate betrayal lie in her own blood?
