ABANDONED. Girl working in a diner serves a boy and his rich friends

[Mai]

This book came up searching online and the plot sounds like your description!
The Debt by Charlotte Byrd.

"When 25 yr. old waitress, Brielle, receives a mysterious check for $250,000, she uses the money to pay for her mother's very expensive cancer treatment, saving her life.
Two years later, she is called to pay back her debt. All she has to do is travel to an isolated mansion and work for one year as a personal assistant to an arrogant asshole whom she hates.
Wyatt Wild is a gorgeous alpha billionaire playboy who is not used to girls saying no to him. He has bedded models, actresses and socialites and then a waitress from some crappy roadside cafe dares to reject him. Who does she think she is?"

Kayleigh deleted her original post but is still in the group. In the absence of other posts by her in the thread, I'm going to move this to Abandoned. If she rejoins the thread we can move it out of Abandoned.
