Married to My Sis' Mafia Fiance
(2026)(A book in the Forbidden Mafia Kings series)
A novel by Alexis Lee
The ruthless mafia boss I've secretly loved just pinned me against the fitting room wall.
Blind drunk, he claims my body, whispering his fiancée's name.
The problem? His fiancée is my sister.
And when she vanishes on their wedding day, I’m forced to become his substitute wife.
He locked me in the attic on our wedding night.
But hatred bleeds into obsession.
Cruel glares ignite into possessive heat.
Brutal commands soften into breathless kisses in the dark.
I believed he finally saw me.
I smile at the positive pregnancy test, planning to surprise him on his birthday.
Then, my sister returns.
Standing outside his office door, clutching his gift, I hear the words that shatter my foolish heart forever:
‘She’s just a substitute.’
I leave my wedding ring on the nightstand and walk out with nothing but the secret growing inside me.
Dante thought I was disposable.
But when he discovers the secret I took with me, the lethal boss won't just hunt me down.
He’ll burn his own empire to the ground to drag me back.
