Ruthless Sinner by Erika Wilde

Dark, dangerous mafia soldiers like Marco Russo were made men, but luckily for me, they weren’t made for marriage. Which made my job of seducing him so much easier.
It was supposed to be a simple undercover operation. One that required me to work in a strip club in order to get close to Marco and do whatever it took to coax him to spill his family’s secrets. Our attraction was undeniable, so establishing a relationship with him was the easy part. Enticing him to share sensitive information took far more finesse.

But during all those steamy nights we shared I learned enough to take down his family. I also made the stupid mistake of falling for the enemy and now I was going to have to make a choice.
My head or my heart.
My job or my love.
My end or my beginning.
Because once Marco realized who I was and how I’d deceived him, he’d have a choice to make, as well
To let me live . . . or to kill me to prove his loyalty to his family.
