His Passerotta. Gruco Crime Family, #6

I didn't know my boss was a criminal.  Well, not for certain. I've been crushing on Anthony Gruco for months, but the idealized version of him I'd conjured in my mind doesn't even resemble the Italian mafia capo I meet the night I break into his restaurant.  I'm only there to retrieve the phone I left in my locker, but I hear voices in the next room and am stupid enough to listen. By the time I realize it's a mob meeting, it's too late.
They catch me, and despite all my newfound knowledge, I still beg Anthony for help.  Now I'm in the trunk of his car, wondering one thing. What do you do when the man of your dreams might be the villain of your nightmares?  A note about Gruco Crime Famiy:This is an 18+ standalone mafia romance series with varying tropes and heroes with diverse personalities, intentions, and tolerances for violence.
