Blurred Loyalties by B. Willow

Two things are guaranteed in the world Beatrice has been born into.
Marriage and death.
Being the eldest child is never easy, it’s a whole lot harder being the firstborn and female.
But when tragedy strikes the Gallo family, Beatrice is left unmarried.
Carrying the weight of her family on her shoulders, Beatrice is forced into an engagement to ensure their safety.

Leonardo Bianchi is heir to the biggest crime organization on the east coast.
He’s no white knight.
But when his brother begs him to marry his best friend and the woman he loves, to save her from an unthinkable future.
Leonardo has one condition.
He won’t share his wife.
