He was promised a bride and has no idea the wrong sister is walking down the aisle.
When my sister runs off on her wedding day, I'm forced to take her place.
Emilio Lastro is a brutal Mafia capo, known for his carnage. He doesn't know I'm not the bride he signed for. I'm terrified of what he'll do when he pulls back the veil and finds me instead.
But that's not the worst part. I'm not only replacing my sister. My family has also secretly instructed me to kill him.
Will my sin be killing him… or giving the monster my heart?
