At the Boss’s Mercy by Sam Crescent

Abigail Gardner is done being the “safe” girl her cheating ex claimed she was. To celebrate a year of freedom, she does something reckless—she walks into an exclusive sex club and spends one unforgettable night with a masked stranger.
Then the mask comes off.
Her mystery man is Roman Brown. Her older, billionaire boss.
Roman has wanted Abigail for far longer than she realizes, and now that he’s finally had a taste of her, he’s not willing to let her go. Abigail agrees to one rule: inside the office, they stay professional. Outside of it? Roman plans to worship every inch of her.

What starts as a no-strings fling quickly turns into something far more dangerous. Because Roman has secrets. Secrets tied to Abigail’s past. And when the truth comes out, their explosive chemistry may not be enough to save them.
