Vow of Darkness by Ivy Davis

I was forced to save my father by marrying a monster.

Gabriel Romano kidnapped my father for a petty crime.
I’m the only one who can take my father’s place.
So I make a deal with the devil:
I’ll stay with Gabriel forever if he lets my father go.
What I’m not prepared for is to be a mafia man’s wife.
Gabriel brings out a desire in me I’ve never felt
But he also terrifies me.
How can I love my husband when he holds my father’s life in his hands?
I’m stuck in a marriage I can’t get out of.
The only way is to move in deeper but that means giving my heart to a beast.
Or it could mean giving my life over to the man I love.
