Marriage of Sin: An Arranged Marriage Mafia Romance (Deadly Sins)

A standalone arranged marriage mafia romance where the black cat heroine meets her match — an obsessed golden retriever hero in a killer's body.

My father built an empire in blood.
I spent twenty-two years pretending it wasn't mine.
Then he was gunned down at a Boston charity gala, and everything I fought to escape came crashing back into my life.
Including the marriage contract he signed without my permission.
Now I'm legally bound to Lochlan Molloy, the devastatingly handsome heir to Boston's most powerful Irish crime family. According to our fathers, our marriage will unite two empires and stop a war with the Russian Bratva.
I call it extortion.
I'll wear the ring.
I'll play the dutiful wife.
But I refuse to share his bed, his home, or my heart.
There's just one problem.
The man I married isn't the ruthless mafia prince I expected.
He's patient. Protective. Infuriatingly honorable. The kind of man who remembers how I take my coffee, waits up for me after midnight meetings, and stands between me and every bullet meant to end my life.
The closer we become, the harder it is to remember this marriage was never supposed to be real.
As enemies close in and betrayal comes from the people I trusted most, I'll have to decide what matters more—protecting the empire I've inherited or risking everything for the man I was never supposed to love.
Because in our world, love is the most dangerous weakness of all.
And someone is willing to burn Boston to the ground to make sure we never get a happily ever after.
