I took my sister’s place to save my family. Now I am living a life that could destroy me. I never wanted anything to do with the mafia. But when my twin sister vanished without a word, I stepped into her world and became her… the wife of Rowan, a man people fear and never question.
Every day, I live a lie. His son, Dante, looks at me like I am his mother, and something inside me breaks every time he says in a low voice that l look like his mom. But not everyone is fooled.
Rowan’s family watches me too closely. They see what does not belong and they are waiting for me to slip so they can get rid of me for good.
I tell myself I can handle it. That I just need to survive long enough to protect the people I love.
But I am losing control. Because the man I was never meant to love is starting to look at me differently. And the worst part is… I think I am falling for him too.

After I retired, I was willing to do the dirtiest work at a small auto repair shop—just to give my sick daughter an ordinary childhood.
I endured my mother’s insults, my eldest brother’s wage cuts, my younger brother’s extortion.
But they actually joined forces to steal my daughter’s life-saving money for gambling, then sold me into an illegal mine to pay off their debts.
When the iron chain locked around my wrist, when my daughter cried in despair, the killing intent that had slept in my blood for three years finally woke up completely.
They had no idea I was once the iron-blooded God of War—commander of a million troops, the name that made enemy nations tremble.

In their eyes, my wife Emma—an Ivy League tenured professor in biological sciences—is ruthless, rational, and obsessively clean.
For seven years, even when she washed her hands, she would only ever touch the right-side sink—hers.
Until that night at 3 a.m., when I pulled a strand of sandy-golden short curl—hair that belonged to neither of us—out of my men’s shower loofah.
And around the neck of a pre-med student named Lucas, I saw the antique silver cross my dying father left in my hands.
When I confronted her, my always-icy wife protected the little homewrecker, slapped me across the face, and called me a jealous, controlling chauvinist.
She thought I’d swallow it like a coward.
But she forgot: as a top cardiothoracic chief, the thing I do best is cutting out tumors.
