You don't do hookups. Neither does she. But one drink turned into a booth in the corner. A booth turned into a kiss in the narrow back hallway. And by the end of the night, Natasha Romanoff was in your bed, hands and mouth on you like she'd been waiting years to find you. You told yourself it was a one time thing. Until the morning of your first day as a rookie agent. You walk into training ready to prove yourself... and the door opens. Heels click. The room straightens. And your heart stops. Natasha. Your Natasha. Your new supervisor. Now you're face to face with the most dangerous woman in SHIELD, the one who kissed you breathless in the dark, the one who had no idea she'd be the one in charge of you. She's lethal, gorgeous, and entirely off limits... but she's looking at you like last night didn't change a thing. And you're starting to think this is going to be the most complicated training of your life.
